You have two options:
1. Use the ccd driver (might be harder to set up, but easier to
understand). This concatenates two partitions to create a single
"striped" disk.

2. Split /var into separate partitions (i.e., use a different file
system for /var, /var/spool, etc...). This requires a good estimate of
where the load on the filesystem will come from, both in terms of I/O
load and file size.

The second option should work while in sysinstall. To set up ccd,
however, you first need to get a working system, then modify it (see man
ccd, ccdconfig).

Hope this helps,
