/ is a memory filesystem here at my site.
/var should be large enough, to hold
	- logfiles (think about http statistics as well)
	- mail spool
	- kernel dumps
	- printer queues
	- ...
Creating separate filesystems for /usr/obj can be an advantage
for fast writing/removing temporary files and directory during
the build process of the operating system ... On /usr I wouldn't
trust the asynchronous mount option ;-)

News should get a partition of it's own, because you need more
inodes and I'd think about setting the fs up with 4096/512
block-/fragsize.

/dev/sd0a on / (local)
/dev/sd0s2f on /usr (local)
/dev/sd0s2e on /var (local)
/dev/ccd0c on /obj (asynchronous, local, noatime)
/dev/ccd1c on /news (local, noatime)
/dev/ccd2c on /www (local, noatime)
/dev/ccd3c on /home (local)
procfs on /proc (local)
kernfs on /kern (local)
mfs:36 on /tmp (asynchronous, local, noatime)

And no, sysinstall shouldn't do a dummy installation, which
creats "lame" links, only because people don't plan their
internet sites correctly.
