This makes it obvious that those functions are only usable in the initramfs. Also, add a warning when noauto, nofail, or automount is used for the root fs, instead of silently ignoring. Using those options would be a sign of significant misconfiguration, and if we bother to check for them, than let's go all the way and complain. Other various small cleanups and reformattings elsewhere.
