Hi,
could it be that we are starting udev too early in the boot process?
http://bugs.openembedded.org/show_bug.cgi?id=5090
http://bugs.openembedded.org/show_bug.cgi?id=5246
Above two bug reports whose effects I can confirm would suggest that to
me. But I'm not sure about the side-effects of starting udev later than
where it currently is at. Anybody care to comment?
Regards
Rolf

My opinion is the dev cache code is wrong, it should cache into /dev which
is the only place guaranteed to be writeable. There then should be a second
init script later in the boot process which moves this to /etc/

In fact to follow on from my mail, as 2.6.32 devfs has reapperred in the
kernel we could do away with the caching on modern kernels totally.
