I didnt change anything... it just stopped working :( I am doing
non-fbsd work these days so I really cannot imagine what changed

I dont have anything like that set... it looks like a bug in kernel/linux_base
because the trace looks like:

Jan  8 18:57:59 witten kernel: linux(1582): open(/lib/tls/librt.so.1, 0x0, 0x0)
Jan  8 18:57:59 witten kernel: linux(1582): open returns error 2
Jan  8 18:57:59 witten kernel: linux(1582): open(/compat/linux/lib/librt.so.1, 0x0, 0x0)
Jan  8 18:57:59 witten kernel: linux(1582): open returns error 0
Jan  8 18:57:59 witten kernel: linux(1582): open(/usr/lib/tls/librt.so.1, 0x0, 0x0)
Jan  8 18:57:59 witten kernel: linux(1582): open returns error 2
Jan  8 18:57:59 witten kernel: linux(1582): open(/usr/lib/librt.so.1, 0x0, 0x0)
Jan  8 18:57:59 witten kernel: linux(1582): open returns error 0
Jan  8 18:57:59 witten kernel: linux(1582): exit_group(127)

ie. it opens the right library but IGNORES it and the iterates through the rest
and then stops on fbsd library saying that its not compatible...

from within jail it works (because it must stop at the correct library). I tried
to reinstall fc4 base but it didnt help. I see this behaviour on both fc4 and gentoo
base. I even tried to cvsup to yesterdays sources (when it worked for me) but it
didnt help either.. I am really hopeless ;(
