My plan IS to run Linux binaries directly on FreeBSD using the Linux ABI. I
just want to do it in jails. Since all the software I plan to run in the
jails will be Linux, I'm wondering if I can get away without using anything
The debian port is something else. Even if it has jails support it's not
mature enough for what I have in mind and I'd like the FreeBSD host to be

My boss is actually a proponent of FreeBSD as well, but there are many man-
hours invested in getting the current infrastructure to work smoothly (which
it does), and we don't have the time or the motivation to do a wholesale
switchover at this point. A gradual switch is more likely, especially once
some things like SUJ have time to mature in the tree.
