I just noticed a regression - immediately after updating
kernel from 2.6.32 to 2.6.35 (I skipped .33 and .34).
Namely, unshare(CLONE_NEWNS) stopped workin from within
a container, like this:

unshare(CLONE_NEWNS)              = -1 EINVAL (Invalid argument)

There's no other fancy stuff going on around, just plain
unshare and exec a new shell.

What's wrong with 2.6.35 in this context?

Thanks.
