Its great if a user floods /tmp and you email system wont accept email anymore because the /var/spool/mail and /var/spool/mqueue is full.

See your statement above - You declare HP and AIX unreliable which is the opposite of what i feel like working with both. I like the way AIX asks me to grow /usr automatically on software installation e.g. through smit.

I am not a fan of enabling "autogrow" all the time but IF a filesystem gets full i want to be ABLE to grow it or even spread on another hot plugged hd added to my VG.

What do you do if you would like to give a user 30MB in /home and 100MB for /var/spool/mail ... no way of doing this in a single filesystem with quota.
