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
