this only applies to automatic partitioning.  if you set up
partitions manually, it doesn't apply.  what do you think
automatic partitioning should do?  should it only be of use
for installing the distribution, or should it be of general use?

if your answer is the former, then prep is pretending to
be general, when it's not.  and 200mb might be too small.

if your answer is the latter, then 200mb might be too large,
it might make sense to sometimes set up a very small fossil
for stand-alone servers.  say, a stand-alone secstore server.

why not remove swap from the standard list of partitions?  it is
a very rare machine today that needs swap, and due to the locking
in port/page.c it's pretty easy to wedge your machine with it.

the oldest bootable machine i have is a pentium ii (dual processor)
with 256mb of memory.  even that needs no swap.  last time i was
at the computer history museum, i saw one of its processors on display!

i'm sure there are some older machines with less memory still running,
but right now we're just making the common case hard by configuring
swap.
