OT: Solaris Jumpstart from FreeBSD

[Brian J. McGovern]

I realize this email is _really_ old, but did anyone ever get jumpstarts
running from FreeBSD? I'm looking at setting up a jumpstart server here, and
have a number of FreeBSD boxes laying around that would be easier to use
than my Solaris sytems.
