Muhammad Hamza 97a4c50fa3 udev-extraconf/mount.sh: only mount devices on hotplug

fdisk from util-linux (2.31.1) and above allows the user to
manipulate an already mounted device. In order to achieve this
functionality it issues a BLKRRPART (block device re-read part)
ioctl and in response the kernel generates remove/change/add
events if the device is not mounted (manually unmounted etc)
which are caught and processed by udev. This causes our auto-mounter
to remount everything because it does not keep track and things
go out of control.
Differentiating between types of remove events such as the one
described above (generated by BLKRRPART) and one where the device
is physically plugged out is only possible using the DEVPATH variable
which is cleaned up only when the device is actually plugged-out.
This fixes the above anomaly by only mounting a device in add event
which is cleaned up properly (tmp cache deleted) in the remove event
or is not present in the tmp cache while making use of the DEVPATH
variable during the remove action.

Poky

Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.

Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.

As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.

The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/

OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Contribution Guidelines

The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.

A guide to submitting patches to OpenEmbedded is available at:

https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded

There is good documentation on how to write/format patches at:

https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines

Where to Send Patches

As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:

OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):

Git repository: https://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org

BitBake (files in bitbake/):

Git repository: https://git.openembedded.org/bitbake/
Mailing list: bitbake-devel@lists.openembedded.org

Documentation (files in documentation/):

Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
Mailing list: docs@lists.yoctoproject.org

meta-yocto (files in meta-poky/, meta-yocto-bsp/):

Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
Mailing list: poky@lists.yoctoproject.org

If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
