Looking at this it seems that it would explain the odd set of errors I
got reported during bootup under 2.5.12 -- a set of "permission denied"
errors from find(1) where, under 2.5.6, none had occurred.

These were on directories that are not owner by root, with the process
running as root.

I can look deeper into the problem, though, if you don't think that this
is the cause of it.

Regards,
Daniel
