I've made a quick look-see through my copies of "The Complete FreeBSD" and
"Absolute BSD" and can't find the reference, but I recall reading
somewhere in my 4.x days that FreeBSD used a different algorithm to write
to the /var directory, if it was on its own filesystem, because /var was
written to a lot (holding logs and all.) Because of this, and all the way
up to 6.2 today, I put /var on its own filesystem, after / and swap.
Where the old AIX wonks used to call the "outer middle" of the disk. Was
this different algorithm really the case? And, now with UFS2, is it still
the case? I still put pgsql/data on /var.
