When I set up the initial FreeBSD install
to host io7m.com, I didn't realize how trivial
it was to use ZFS as the root
partition. Having used this option several times since, I now wish I had
done this for the io7m VPS. I might spin up
a new VPS over the next few days with a ZFS root partition, copy the
configuration data over to the new VPS, and then reconfigure DNS to
point to the new system. If there's a mysterious outage, this will
be the reason why.
