Since my call for testing the extended linuxulator in FreeBSD-current we got not much negative responses. Ping doesn’t work on the linux side (fixed in p4), ordinary network connections (e.g. downloading some stuff) works fine. There seems to be a deadlock on SMP systems when compiling a lot of stuff in parallel (e.g. using emerge in a gentoo–chroot with MAKEFLAGS=-j4), this is being under investigation by Roman. Compiling stuff serially on an UP system works just fine so far.
I’m wondering if the lack of responses means that everything is running just fine, or that nobody is giving it a try. So far the daily use of linux programs (acroread, linux-firefox, …) with 2.6.16 compatibility seems to just work fine on UP and SMP systems and currently I don’t see a reason to not switch the default in i386 in a week.
Jung-uk Kim is working on the linux-TLS on amd64 part. ATM he is chasing bugs. It looks we can get feature parity between i386/linux and amd64/linux32 soon.
Intron did send in a patch for the linux-aio stuff. Now I just need to get time to have a look at it.
