Thank you for the kind words. :)

As much as I want to agree with you, I can't quite do so.
There are (to the best of my understanding) solid reasons why no other
installer has made it into base. This doesn't necessarily mean that
sysinstall is the final answer, though. Eventually, in my opinion,
sysinstall needs to be replaced. It tries to do more than it should. For
example, one of the things I'd like to see removed is the upgrade option -
although I'm expecting quite a bit of backlash on that, so we'll see if that
happens. I also don't think it should manage configuring rc.conf beyond
network interfaces/hostname. The network services configuration is a mess. I
don't think enabling the NFS server via sysinstall even works at this point.
That aside, the code for sysinstall isn't really that bad, although it's
been more of a history lesson than I initially expected. It was clearly
written with the restrictions of older technology in mind. Bringing it
completely up to date with current technology (devfs, gpt, zfs, whatever) is
going to be such an extensive rewrite that it's true, one might as well
write a new installer altogether.
Then again, maybe I just like playing devil's advocate. :)
