Great, now I'm not as scared as before. Maybe an opportunity for Roman
to get his *at() into the tree (I don't know where the bottleneck is
currently, maybe the functions are under review)...

2.6.21 is not supported by us, 2.6.16 is targeted by the current work
in the linuxulator, but there are some syscalls missing (see
http://wiki.freebsd.org/linux-kernel and
http://wiki.freebsd.org/linux-kernel/ltp for more).

Thanks, for investigating.

Depends upon your interests... the wiki lists some things which need
investigation/fixes, maybe you can have a look and try to find causes
of failing LTP tests or maybe you can even provide fixes. Feel free to
jump in and give it a try. :)

Bye,
Alexander.
