I recently did a manual upgrade of a NetBSD installation on an
old PC with a slow disk. Since the distribution sets contain
lots of relatively small files, re-mounting the file systems with
the "async" option before unpacking helped quite a bit on the
speed of the upgrade. After booting the new kernel single-user
and setting it up for the upgrade I did
# mount -u -o async /
and similarly for /usr. After the upgrade I did
# mount -u -o noasync /
and similarly for /usr.
Where I live power failures are relatively rare, so I found the
risk of doing this acceptable. Your mileage may vary.
This should however be relatively "safe" to do on a fresh
install, perhaps it's an idea for sysinst? Just need to remember
the sync and the remount, though...
