Maybe I'm just used to the old SysV systems, but every time I
see /etc/mtab as a link to something on /var I want to scream.

We also have to remember that historicaly the homedir for root was
/. Even these days we still see it as /root. I'm sure you remember
all the reasons for it not being on /home, so I won't get into that.

Anyway, I agree that ideally the changeable areas should be restricted,
or at least grouped, to simplify management.

It is, of course, theoreticaly possible to have / mounted ro. Will take
a good bunch of symlinks, tho, so I would not recomend it to anyone.
