Lots of things report this actually - if you look in your log files
you'll see lots of "utmp file is locked/read" - also in bootup
messages there will be a "can't lock <whatever>".

I have a feeling this might just be generally broken in the revision
of the kernel we're using, though it could be a problem with LFS in
our glibc if it is trying to use fcntl64().

I suspect that our LFS stuff is generally broken (lseek64() is, at
least) and plan to investigate further on Tuesday.
