Just as another data point:  I do *not* have a separate partition
for /usr and /var (*), so my '/' partitions are similar in size to
the standard setup.  On two machines that I can quickly check here,
I have a 300-meg '/' on one, and a 470-meg '/' on the other.  My
other systems probably have a smaller root partition, because these
two machines are my two most-recent builds.

I have been running with softupdates enabled on '/' for a long time,
and as far as I know it hasn't caused me any problems since maybe
5.2.1.  It did used to cause me occasional problems a few years ago,
but I can't remember any recent problems.

I must admit I'm a little uneasy moving /usr and /var into '/', just
because I'm so used to the way it is.  I really *like* having /var as
a separate partition.  But hard disks are huge compared to how they
used to be, so I don't mind having a 500-meg '/'.  I *do* save the
kernel.debug information in my /boot/kernel's, and my root partition
is still under 50% full.

(* - Except for my PowerPC machine...  That machine has everything
      in '/' except for one large empty partition on '/usr/obj', and
      a memory-disk partition sitting on /tmp_md ).
