[ndbug] indraprastha upgrade

[N.J. Thomas]

The box that hosts the NDBUG website and mailing lists, indraprastha,
will be taken down for a bit while I wipe and reinstall the OS.

It's currently running FreeBSD 12.2-RELEASE, we are just reinstalling to
upgrade to ZFS. This is one of the last of my machines that is still
running UFS.

(Interestingly, we've only ever done in-place upgrades for the last five
years. I'm really happy freebsd-upgrade has worked flawlessly during that
time.)
