Has anybody tried this? The changes in the FreeBSD kernel which allow to emulate (parts of) linux 2.6.16 are only in -current, not in 6.x or -stable. And even on -current not every system call from 2.6.16 is available. It is still in development and there are still (known and unknown) bugs. My intend is to backport some bugfixes for 2.4.2 in -stable, but I don't have a timeframe for this. It's somewhere on my TODO list, and will do it when I get time to do it. I don't expect to do this in the near future. There's absolutely no intend to backport the 2.6.16 stuff to -stable so far (it's not even fully usable in -current). The linuxulator on amd64 is not on the same level as the i386 version yet. If you want to use it on amd64 you either have to run with custom patches (you can get them from wiki.freebsd.org/linux-kernel) or you have to wait a little bit until TLS and futexes are merged. This is scheduled to be committet ASAP. Using 2.6.16 on -current may or may not work. If you give it a try make sure you test it carefully before you make productive use of it.
