something mess-up with /dev/null permissions

[Pal, Laszlo (private)]

Hi,

Recently I've discovered a strange thing... some rule/program or
whatever changing the access rights of /dev/null to

crw-------. 1 root root 1, 3 May 20 11:57 /dev/null

and some of the part of Fedora does not like it :)

After I change back to 666, everything is fine again, however after boot
I have again the "wrong" permission

is this a bug or feature? :) What can cause this? After google the
problem, I can find some very old bug, so maybe it is back again

Any idea?

Thx
