Brooks' argument, yes.  rwatson's argument was for mail.

The recommendation I made was to put /var in the root file system
*unless there are good reasons not to do so*.  The issue here is that
automatic partitioning can't take your usage patterns into account.
Where you do need large a /var, it makes sense to have a separate
partition.  But most people create a separate /var, usually too big or
too small, because that's the way it's done.

FWIW, I don't use a separate /var on any of my systems, though there's
certainly an argument to do so.  But I haven't run out of space.

Note also that in this case, an alternative to a separate partition is
to set up quotas.  Not that I do that, either.
