The inconsistancy happens for meon x86_64 too, and also on my ARM boxes.
However I have never had any problem with this before and have never
noticed it on any platform.

There are some mailing list threads about people making mtab a symlink to
/proc/mounts -- I haven't read them all, but if you haven't, it'd
probably be worth a read -- this isn't a new thing!
