This is how it used to be done for first 3 years. The biggest problem was
clearing the mtab file so mount doesn't get all confused when you try to
mount partitions that aren't mounted yet but due to a crash in the previous
session the mtab file doesn't show it.
And clearning /etc/mtab isn't always an option when / is to be mounted
read-only. The only alternative is to tell mount, glibc and other programs
that the mtab file is to be found elsewhere, maybe somewhere in /var as the
mtab hint suggests. But I don't quite agree with that. mtab belongs in /etc
so I wouldn't write the book in such a way that things are patched up and
/etc/mtab moved elsewhere.
Personally I believe the symlink setup's positive points outweigh the real
file setup's negative points. Call it a personal bias but I believe a symlink
is the way to go. Maybe mount should be made more intelligent about loopbacks
but that's a different discussion.
