The revised auto-sizing patch for sysinstall is now available for
both -stable and -current. I changed the /var and /var/tmp target
sizes to 256MB each, and generated a separate patch against -current.
The new target sizes seem to work better for smaller disks (it doesn't
knock them down too as much as it would otherwise), and are obviously
fine for larger disks.
The -current patchset is a commit candidate, the -stable patchset is
an MFC candidate.

TESTING
Testing with VN or MD requires a couple of hacks that are not part of
the official patch set.
In lib/libdisk/disk.c add "vn" to the device_list for -stable,
"md" for -current. recompile and install. Remove the hacks in the
source before continuing so you don't accidently commit it later.
For -current, in usr.sbin/sysinstall/devices.c deviceGetAll() around
line 442 there is an explicit check to weed out "md". Remove the
check (#if 0 it out).
Create a vnode-backed VN or MD device as appropriate (for MD devices
you have to use /usr/bin/truncate to pre-create the file). As long
as you don't actually do anything major with it you can create an
arbitrarily sized vnode backing file on a small filesystem.
sysinstall should then recognize an appropriately configured VN or MD
device. Again, for testing only. Remember to remove the hacks when
done so you don't accidently commit the hacks later.
