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.
