why BSDs got no love

[Astrodog]

I think what we're looking at here is that sysinstall should probably
be replaced... but it works well enough that it doesn't *have* to be
replaced, and most people aren't bothered enough by it to write code
to come up with something new. Certainly, having things like zfs
support in sysinstall would be nice... but most of the people using
zfs boot know the system well enough to do it from the Fixit/LiveFS
shell anyway.

Basically... if you really want to see this change, I think you're
gonna have to do it yourself.
