1) "touch /forcefsck" then rebooting isn't the same as running fsck on
a mounted partition. And it also only works for "/".

2) "touch /forcefsck" is superceded on systemd by passing
"fsck.mode=force [fsck.repair=...]" on the kernel cmdline.

3) _IF_ "fsck from grub menu" means selecting to fsck "/" from the
friendly-recovery menu that's displayed in single-user mode fails
because "/" is mounted, then there's a bug in that package. (I don't
use it so I can't check.)
