Subject: [PATCH] generators: rename add_{root,usr}_mount to
add_{sysroot,sysroot_usr}_mount
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.
(cherry picked from commit 2e8522767e27d5686206794c69e0aa95da6e798b)
Cherry-picked from: 2e85227
Resolves: #1222517
