+OE-Core aims to be able to provide basic LSB compatible images. There
+are some challenges for OE as LSB isn't always 100% relevant to its
+target embedded and IoT audiences. 
+
+One challenge is that the LSB spec is no longer being actively
+developed [https://github.com/LinuxStandardBase/lsb] and has 
+components which are end of life or significantly dated. OE 
+therefore provides compatibility with the following caveats:
+
+* Qt4 is provided by the separate meta-qt4 layer. Its noted that Qt4 
+  is end of life and this isn't something the core project regularly 
+  tests any longer. Users are recommended to group together to support
+  maintenance of that layer. [http://git.yoctoproject.org/cgit/cgit.cgi/meta-qt4/]
+
+* mailx has been dropped since its no longer being developed upstream 
+  and there are better, more modern replacements such as s-nail 
+  (http://sdaoden.eu/code.html) or mailutils (http://mailutils.org/).
+
+* A few perl modules that were required by LSB 4.x aren't provided:
+  libclass-isa, libenv, libdumpvalue, libfile-checktree,
+  libi18n-collate, libpod-plainer.
+
+* libpng 1.2 isn't provided; oe-core includes the latest release of libpng
+  instead.

-
-Support for additional devices is normally added by creating BSP layers - for
-more information please see the Yocto Board Support Package (BSP) Developer's
-Guide - documentation source is in documentation/bspguide or download the PDF
-from:
-
-   http://yoctoproject.org/documentation
-
-Support for physical reference hardware has now been split out into a
-meta-yocto-bsp layer which can be removed separately from other layers if not
-needed.
-
-

-================
-
-The following consumer devices are supported by the meta-yocto-bsp layer:
-
-  * Intel x86 based PCs and devices (genericx86)
-  * Ubiquiti Networks EdgeRouter Lite (edgerouter)
-
-For more information see the device's section below. The appropriate MACHINE
-variable value corresponding to the device is given in brackets.
-
-
-
-                      Specific Hardware Documentation
-                      ===============================
-
-
-Intel x86 based PCs and devices (genericx86*)
-=============================================
-
-The genericx86 and genericx86-64 MACHINE are tested on the following platforms:
-
-Intel Xeon/Core i-Series:
-  + Intel NUC5 Series - ix-52xx Series SOC (Broadwell)
-  + Intel NUC6 Series - ix-62xx Series SOC (Skylake)
-  + Intel Shumway Xeon Server
-
-Intel Atom platforms:
-  + MinnowBoard MAX - E3825 SOC (Bay Trail)
-  + MinnowBoard MAX - Turbot (ADI Engineering) - E3826 SOC (Bay Trail)
-    - These boards can be either 32bot or 64bit modes depending on firmware
-    - See minnowboard.org for details 
-  + Intel Braswell SOC
-
-and is likely to work on many unlisted Atom/Core/Xeon based devices. The MACHINE
-type supports ethernet, wifi, sound, and Intel/vesa graphics by default in
-addition to common PC input devices, busses, and so on.
-
-Depending on the device, it can boot from a traditional hard-disk, a USB device,
-or over the network. Writing generated images to physical media is
-straightforward with a caveat for USB devices. The following examples assume the
-target boot device is /dev/sdb, be sure to verify this and use the correct
-device as the following commands are run as root and are not reversable.
-
-USB Device:
-  1. Build a live image. This image type consists of a simple filesystem
-     without a partition table, which is suitable for USB keys, and with the
-     default setup for the genericx86 machine, this image type is built
-     automatically for any image you build. For example:
-
-     $ bitbake core-image-minimal
-
-  2. Use the "dd" utility to write the image to the raw block device. For
-     example:
-
-     # dd if=core-image-minimal-genericx86.hddimg of=/dev/sdb
-
-  If the device fails to boot with "Boot error" displayed, or apparently
-  stops just after the SYSLINUX version banner, it is likely the BIOS cannot
-  understand the physical layout of the disk (or rather it expects a
-  particular layout and cannot handle anything else). There are two possible
-  solutions to this problem:
-
-  1. Change the BIOS USB Device setting to HDD mode. The label will vary by
-     device, but the idea is to force BIOS to read the Cylinder/Head/Sector
-     geometry from the device.
-
-  2. Use a ".wic" image with an EFI partition
-
-     a) With a default grub-efi bootloader:
-     # dd if=core-image-minimal-genericx86-64.wic of=/dev/sdb
-
-     b) Use systemd-boot instead
-     - Build an image with EFI_PROVIDER="systemd-boot" then use the above
-       dd command to write the image to a USB stick.
-
-
-Texas Instruments Beaglebone (beaglebone)
-=========================================
-
-The Beaglebone is an ARM Cortex-A8 development board with USB, Ethernet, 2D/3D
-accelerated graphics, audio, serial, JTAG, and SD/MMC. The Black adds a faster
-CPU, more RAM, eMMC flash and a micro HDMI port. The beaglebone MACHINE is
-tested on the following platforms:
-
-  o Beaglebone Black A6
-  o Beaglebone A6 (the original "White" model)
-
-The Beaglebone Black has eMMC, while the White does not. Pressing the USER/BOOT
-button when powering on will temporarily change the boot order. But for the sake
-of simplicity, these instructions assume you have erased the eMMC on the Black,
-so its boot behavior matches that of the White and boots off of SD card. To do
-this, issue the following commands from the u-boot prompt:
-
-    # mmc dev 1
-    # mmc erase 0 512
-
-To further tailor these instructions for your board, please refer to the
-documentation at http://www.beagleboard.org/bone and http://www.beagleboard.org/black
-
-From a Linux system with access to the image files perform the following steps:
-
-  1. Build an image. For example:
-
-     $ bitbake core-image-minimal
-
-  2. Use the "dd" utility to write the image to the SD card. For example:
-
-     # dd core-image-minimal-beaglebone.wic of=/dev/sdb
-
-  3. Insert the SD card into the Beaglebone and boot the board.
-
-Freescale MPC8315E-RDB (mpc8315e-rdb)
-=====================================
-
-The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
-software development of network attached storage (NAS) and digital media server
-applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
-includes a built-in security accelerator.
-
-(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
-same board in an enclosure with accessories. In any case it is fully
-compatible with the instructions given here.)
-
-Setup instructions
-------------------
-
-You will need the following:
-* NFS root setup on your workstation
-* TFTP server installed on your workstation
-* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your 
-  PC to UART1
-* Ethernet connected to the first ethernet port on the board
-
---- Preparation ---
-
-Note: if you have altered your board's ethernet MAC address(es) from the
-defaults, or you need to do so because you want multiple boards on the same
-network, then you will need to change the values in the dts file (patch
-linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
-you have left them at the factory default then you shouldn't need to do
-anything here.
-
-Note: To boot from USB disk you need u-boot that supports 'ext2load usb'
-command. You need to setup TFTP server, load u-boot from there and
-flash it to NOR flash.
-
-Beware! Flashing bootloader is potentially dangerous operation that can
-brick your device if done incorrectly. Please, make sure you understand
-what below commands mean before executing them.
-
-Load the new u-boot.bin from TFTP server to memory address 200000
-=> tftp 200000 u-boot.bin
-
-Disable flash protection
-=> protect off all
-
-Erase the old u-boot from fe000000 to fe06ffff in NOR flash.
-The size is 0x70000 (458752 bytes)
-=> erase fe000000 fe06ffff
-
-Copy the new u-boot from address 200000 to fe000000
-the size is 0x70000. It has to be greater or equal to u-boot.bin size
-=> cp.b 200000 fe000000 70000
-
-Enable flash protection again
-=> protect on all
-
-Reset the board
-=> reset
-
---- Booting from USB disk ---
-
- 1. Flash partitioned image to the USB disk
-
-    # dd if=core-image-minimal-mpc8315e-rdb.wic of=/dev/sdb
-
- 2. Plug USB disk into the MPC8315 board
-
- 3. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
-
-  $ picocom /dev/ttyUSB0 -b 115200
-
- 4. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
-
- 5. Optional. Load the u-boot.bin from the USB disk:
-
- => usb start
- => ext2load usb 0:1 200000 u-boot.bin
-
-    and flash it to NOR flash as described above.
-
- 6. Set fdtaddr and loadaddr. This is not necessary if you set them before.
-
- => setenv fdtaddr a00000
- => setenv loadaddr 1000000
-
- 7. Load the kernel and dtb from first partition of the USB disk:
-
- => usb start
- => ext2load usb 0:1 $loadaddr uImage
- => ext2load usb 0:1 $fdtaddr dtb
-
- 8. Set bootargs and boot up the device
-
- => setenv bootargs root=/dev/sdb2 rw rootwait console=ttyS0,115200
- => bootm $loadaddr - $fdtaddr
-
-
---- Booting from NFS root ---
-
-Load the kernel and dtb (device tree blob), and boot the system as follows:
-
- 1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
-    files from the tmp/deploy directory, and make them available on your TFTP
-    server.
-
- 2. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
-
-  $ picocom /dev/ttyUSB0 -b 115200
-
- 3. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
-
- 4. Set up the environment in U-Boot:
-
- => setenv ipaddr <board ip>
- => setenv serverip <tftp server ip>
- => setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
-
- 5. Download the kernel and dtb, and boot:
-
- => tftp 1000000 uImage-mpc8315e-rdb.bin
- => tftp 2000000 uImage-mpc8315e-rdb.dtb
- => bootm 1000000 - 2000000
-
---- Booting from JFFS2 root ---
-
- 1. First boot the board with NFS root.
-
- 2. Erase the MTD partition which will be used as root:
-
-    $ flash_eraseall  /dev/mtd3
-
- 3. Copy the JFFS2 image to the MTD partition:
-
-    $ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
-
- 4. Then reboot the board and set up the environment in U-Boot:
-
-    => setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
-
-
-Ubiquiti Networks EdgeRouter Lite (edgerouter)
-==============================================
-
-The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
-(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
-internal USB pendrive for storage.
-
-Setup instructions
-------------------
-
-You will need the following:
-* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
-  port on the device
-* Ethernet connected to the first ethernet port on the board
-
-If using NFS as part of the setup process, you will also need:
-* NFS root setup on your workstation
-* TFTP server installed on your workstation (if fetching the kernel from
-  TFTP, see below).
-
---- Preparation ---
-
-Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
-In the following instruction it is based on core-image-minimal. Another target
-may be similiar with it.
-
---- Booting from NFS root / kernel via TFTP ---
-
-Load the kernel, and boot the system as follows:
-
- 1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
-    directory, and make them available on your TFTP server.
-
- 2. Connect the board's first serial port to your workstation and then start up
-    your favourite serial terminal so that you will be able to interact with
-    the serial console. If you don't have a favourite, picocom is suggested:
-
-  $ picocom /dev/ttyS0 -b 115200
-
- 3. Power up or reset the board and press a key on the terminal when prompted
-    to get to the U-Boot command line
-
- 4. Set up the environment in U-Boot:
-
- => setenv ipaddr <board ip>
- => setenv serverip <tftp server ip>
-
- 5. Download the kernel and boot:
-
- => tftp tftp $loadaddr vmlinux
- => bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
-
---- Booting from USB disk ---
-
-To boot from the USB disk, you either need to remove it from the edgerouter
-box and populate it from another computer, or use a previously booted NFS
-image and populate from the edgerouter itself.
-
-Type 1: Use partitioned image
------------------------------
-
-Steps:
-
- 1. Remove the USB disk from the edgerouter and insert it into a computer
-    that has access to your build artifacts.
-
- 2. Flash the image.
-
-    # dd if=core-image-minimal-edgerouter.wic of=/dev/sdb
-
- 3. Insert USB disk into the edgerouter and boot it.
-
-Type 2: NFS
------------
-
-Note: If you place the kernel on the ext3 partition, you must re-create the
-      ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
-      cannot read the partition otherwise.
-
-      These boot instructions assume that you have recreated the ext3 filesystem with
-      128 byte inodes, you have an updated uboot or you are running and image capable
-      of making the filesystem on the board itself.
-
-
- 1. Boot from NFS root
-
- 2. Mount the USB disk partition 2 and then extract the contents of
-    tmp/deploy/core-image-XXXX.tar.bz2 into it.
-
-    Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
-    rootfs path on your workstation.
-
-    and then,
-  
-      # mount /dev/sda2 /media/sda2
-      # tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
-      # cp vmlinux /media/sda2/boot/vmlinux
-      # umount /media/sda2
-      # reboot
-
- 3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
-    command line:
-
-    # reboot
-
- 4. Load the kernel and boot:
-
-      => ext2load usb 0:2 $loadaddr boot/vmlinux
-      => bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)

+                multiple classes, separate them with spaces.
+                The following example shows how to inherit both the
+                <filename>buildhistory</filename> and <filename>rm_work</filename>
+                classes:
+                <literallayout class='monospaced'>
+     inherit buildhistory rm_work
+                </literallayout>

-                If necessary, it is possible to inherit a class
-                conditionally by using
-                a variable expression after the <filename>inherit</filename>
-                statement.
+                An advantage with the inherit directive as compared to both
+                the
+                <link linkend='include-directive'>include</link> and
+                <link linkend='require-inclusion'>require</link> directives
+                is that you can inherit class files conditionally.
+                You can accomplish this by using a variable expression
+                after the <filename>inherit</filename> statement.
                 Here is an example:

-"""
-    This module implements an xmlrpc server for BitBake.
-
-    Use this by deriving a class from BitBakeXMLRPCServer and then adding
-    methods which you want to "export" via XMLRPC. If the methods have the
-    prefix xmlrpc_, then registering those function will happen automatically,
-    if not, you need to call register_function.
-
-    Use register_idle_function() to add a function which the xmlrpc server
-    calls from within server_forever when no requests are pending. Make sure
-    that those functions are non-blocking or else you will introduce latency
-    in the server's main loop.
