TODO: /etc/passwd and /etc/group are not removed yet due to 90mdraid.
dledford said he'll go in and clean this up since he has the hardware
to actually test the mdmon stuff.
This also eliminates --skip-missing. Check scripts should now check
to ensure that any files and settings they will copy from the host
system actually exist when called without arguments.
The check scripts are also updated to not try to source dracut-functions
which(1) is a perfectly good way of checking if a command is on the path.
If we purport to test booting to an md raid, we may as well test it.
We do not need the plymouth module and the normal crypt module to include
duplicate functionality.
