Working towards a more generic bootimg.bbclass, pull out all syslinux specific bits and let syslinux.bbclass manage them directly. This introduces no functional changes to the images constructed and the behavior remains unchanged.

# Creates a bootable image using syslinux, your kernel and an optional
|
|
# initrd
|
|
|
|
#
|
|
# End result is two things:
|
|
#
|
|
# 1. A .hddimg file which is an msdos filesystem containing syslinux, a kernel,
|
|
# an initrd and a rootfs image. These can be written to harddisks directly and
|
|
# also booted on USB flash disks (write them there with dd).
|
|
#
|
|
# 2. A CD .iso image
|
|
|
|
# Boot process is that the initrd will boot and process which label was selected
|
|
# in syslinux. Actions based on the label are then performed (e.g. installing to
|
|
# an hdd)
|
|
|
|
# External variables (also used by syslinux.bbclass)
|
|
# ${INITRD} - indicates a filesystem image to use as an initrd (optional)
|
|
# ${NOISO} - skip building the ISO image if set to 1
|
|
# ${ROOTFS} - indicates a filesystem image to include as the root filesystem (optional)
