This is no longer necessary, since the dependencies of
livecd-net-eth.service are fixed, and for sysvinit the
udev-rule-generator is added already.

For install2, this is needed to work around error 99-cdrom.sh with method:cdrom.
The error shows up with make-initrd-bootchain, but not propagator, as lowmem is
enabled for propagator in this mode.
For rescue, the point is that the latter has become quite large, so by default
it would be better that way.

This targets required udev-rule-generator-net.

Need to support initrd-bootchain in e2k feature.

In the future, will need to modify generate.mk so that can set all
the variables in this config.

xorg-dri-virtio was added via REGEXP to work around the package
missing issue on p9. But it didn't work.

use/ntp was broken by commit 7ef157e2

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.
