Parameter "legacyboot" causes an error:
parted: invalid token: legacyboot

This is an alternative to the initrd-propagator feature.
bootchain-* is a make-initrd features. You should look at the documentation
for it in the make-initrd-bootchain-* packages:
/usr/share/make-initrd/features/bootchain-*/README.md

Workaround to solve the problem of late appearance of the network
interface.

This reverts commit 8f56e8b9.
We will not decide for everyone. This is a crutch, we will use it
only in our area of responsibility (regular builds).

We will not rename the interfaces. So it's still more reliable.
We will use NetworkManager for all desktops, and livecd-net-eth for jeos.

Adds grub "Network installation" submenu and kernel modules to
initrd needed for network booting.

For use them separately.

Set KFLAVOR to un-def for starterkit, as it was before.

This allows you to reset the BRANCH variable by specifying the
'BRANCH=' argument on the command line.

This reverts commit 1da0b164.

- Add COMMON_LISTS variable support by analogy COMMON_PACKAGES.
  Fix use/efi (the list 'base+efi' was not added to rescue, base,
  live)
- kernel: add drivers/soc to VM_INITRDMODULES (needed for rk3399
  support)
- uboot: Added HiFive Unmatched support (thanks jqt4@)
- lib/profile.mk: do not abort build with CHECK=0, if unavailable ARCH
- base+rescue: add eepm (request by lav@)
- stage2: update 50-stage2-sbc-aarch64. Use directories instead of
  specifying modules

So will be the best SBC support.

The commit 99695713 used this variable
even though it didn't exist yet. A good reason to add this variable.

- efi: add mokutil, pesign to COMMON_PACKAGES (for Secure Boot,
  requset by nikel@)
- build.mk: fix build without APTCONF parameter
- image.in/Makefile: fix save-profile (exclude .work)
- bin/metadep-expander: fix output redirection to /dev/null
- bin/metadep-expander: do not abort build, if metapackage not available
- adapt bin/check-pkg-list for mkimage-profiles. Use for build without
  parameter CHECK=0
- reports.mk: fix build with REPORT=1, CHECK=1 and undefined DEBUG
- test.mk: add package availability test in all package lists.
  Usage: make CHECK=1 DEBUG=1 check-all-pkglists.iso
- add missing README for features: mipsel-bfk3, mipsel-mitx, lxc
- ve.mk, vm.mk: replace systemd to use/init/systemd (request by obirvalger@)
- net: Add networkd/resolved and networkd/resolved-stub subfeatures
  (thanks obirvalger@)
- education, slinux, workstation: fix build for non e2k ARCH.
  See also commit 'e2k: add a stub for non e2k%'
- education, slinux, workstation: add use/arm-rpi4 to vm/ targets
  on aarch64, armh
- fix build vm/alt-workstation-cloud
- fix build vm/regular-cnc-rt-efi
- drop armh.conf, target use/slinux/arm and linux-arm list
- cleanup unavailable packages for p10 from package lists

This target and list was only needed for armh.mk. They are no longer needed.

This is not a supported legacy since p8.
