The initramfs writes the overlay upper layer before the SELinux policy
is loaded, so those files are unlabeled_t. On an enforcing image /
itself is unlabeled, and logind, getty and sshd fail.
Label exactly the upper layer paths like el9-diskless does. The root
is an overlay in untethered mode too, so this covers both. chcon comes
from the image, the initramfs has none.
Ported from suse15-diskless, with the differences 16 forces:
- dracut symlinks /lib/dracut/hooks to /var/lib/dracut/hooks, so a hook
shipped at the old path replaces the symlink with a directory
- there is no netconfig or /etc/sysconfig/network to hand the running
address to, so the initramfs writes a NetworkManager keyfile instead.
Without it NetworkManager claims the interface on its own terms and the
tethered root filesystem goes away with the old address, and confignet
never gets the chance to refine anything
- the discovery loop retries without a delay, so a link that takes a
moment to come up can exhaust all 30 tries before the first packet can
go anywhere. Keep asking, as the el9 hook already does
