Public bug reported:
Since December 2010 I had the problem 3 times on my Ubuntu 10.04 LTS
(amd64). I agree to install updates, proposed by the update manager.
After the installation is finished, I am asked to reboot the machine.
Right after the restart of the machine all the file perms are set to
0777, recursively! So this of course affects /usr and /lib, meaning no
setuid flag is set anymore and no 'sudo' is possible anymore. Booting
from a rescue CD and adjusting the perms will be overwritten during the
next startup. My machine runs the Linux system on a separate SATA disk
on ext3. The data is on a 2 disk software RAID (mirror 'md0' using
'mdadm') mounted during startup. I saw several people having the same
problem since about one year, but obviously it applies only to a special
setup. On my second box, which is almost the same (almost a clone of the
first), the problem never occurred. But I can reproduce the problem
easily: simply apply the latest update (say the one of 2011-01-10) and
restart and...'kawumm'.
