I've got a box at Servermatrix that has the default partitioning. Specifically / and /var are 256MB all on one big slice
/dev/ad0s1a 126M 113M 2.7M 98% /
/dev/ad0s1f 252M 696K 231M 0% /tmp
/dev/ad0s1g 72G 7.3G 59G 11% /usr
/dev/ad0s1e 252M 117M 115M 50% /var
procfs 4.0K 4.0K 0B 100% /proc
They're going to fill up pretty soon
This box is running qmail/spamassassin/clamav etc and most of the space in var is eaten up by SA, pyzor and razor. Logs on var.
Thanks!
