Hi,
molly-guard diverts /sbin/{reboot,halt,shutdown,poweroff} that are
normally shipped by systemd-sysv, to replace them with symlinks to
/lib/molly-guard/molly-guard, which is a shell script.
dracut seems to assume things about /sbin/reboot, that are not valid
when molly-guard is installed.
As a result, some functionality is broken, but same as #797314: to be
reported separately, not sure yet if that's caused by dracut vs.
molly-guard, or whether I would have the same problems without
molly-guard).
I'll add more specifics once I've confirmed whether the breakage I see
is caused by molly-guard vs. dracut or not.
Cheers,
