suse-module-tools calls sdbootutil

That is only a guess, but there are references to udevadm in
udev-trigger-generator from suse-module-tools.

Right. Maybe this is a question for mls but I am starting to suspect that maybe
the fix should be placed in sdbootutil and suse-module-tools. I do not know how
libsolv will set the order here, but if the kernel Requires(post)
suse-module-tools, and this makes use of udevadm then suse-module-tools should
make this explicit?

The same for sdbootutil, as it calls bootctl maybe the Supplements systemd-boot
is not enough and should be converted to a Requires.
