I can sympathize. I've been caught by bad partition sizes.

But I never take the default sizes. In particular, I check the size =20
of /var and its sub-partitions carefully. (Seems like nobody uses /=20
tmp that heavily anymore, but /var/tmp gets hit a lot, and /var/log =20
may need to be relatively huge, depending on what the system is =20
doing, etc.)

A partition "wizard" (I hate that term, but you know what I mean.) =20
that would coach new users and remind old users about the effects of =20
freeBSD layout on partition sizes would, I'm sure, be welcome, if you =20=

want to take the trouble. Mind you, simple ruled apportionment would =20
not be sufficient. We would like to have sets of rules, one for a =20
pure web server, one for a basic home-user websurfing, e-mailing, =20
letter-writing coffee-table-top, several for different kinds of =20
firewalls and bridges, ...

And what about older disks, where cylinder sizes, number of reported =20
heads, etc. were meaningful? No, that's probably not relevant except =20
for RAIDs.

(As long as I'm making demands on your time, why not think big? ;^)

Anyway, it could be a useful project, but you'll want to recognize =20
there's a lot of stuff hiding under the surface there.
