Thank you for documenting this.
There's another minor issue with my suggested chroot setups: since /proc
is not mounted in there (unless you do a "mount /proc" after chroot),
the buildworld script is unable to determine the processor count. So it
assumes 1. You can make your builds run a lot faster by either setting
PROCESSORS= in buildworld.conf (set it to 16 for this machine) or
mounting /proc.
Also, it is a good idea to use "screen" for builds that you run on a
remote server. Then possible disconnects won't be an issue.
I hope this helps.
