Subject: [PATCH] generators: rename add_{root,usr}_mount to
1ff636
 add_{sysroot,sysroot_usr}_mount
1ff636
1ff636
This makes it obvious that those functions are only usable in the
1ff636
initramfs.
1ff636
1ff636
Also, add a warning when noauto, nofail, or automount is used for the
1ff636
root fs, instead of silently ignoring. Using those options would be a
1ff636
sign of significant misconfiguration, and if we bother to check for
1ff636
them, than let's go all the way and complain.
1ff636
1ff636
Other various small cleanups and reformattings elsewhere.
