Can you "sudo chmod" to repair your permissions damage? I can send

Indeed I have no machine to check my /dev perm's. If you could send me
the output I'd be much obliged. If you want to send it direct:

I got my fonts back by giving the correct permissions to my home
directory and to .dmrc. Now the only clear problem is being able to log
in as root.
the problem is that three minutes of chmod'ing down into /dev is going
to change permissions on all sorts of stuff in the system. You now
probably have significant numbers of binaries that are 777 and
shouldn't be, for example. If you really want to fix it, you'll have
to look at a whole system tree.
Or reinstall a bunch of packages in hopes that it fixes up the
perms. Find one that you know is wrong and do an
aptitude reinstall <package>
and see what happens. If it fixes the perms, then I'd follow it up
with
dpkg -l | awk '/^ii/ {print $2}' | xargs aptitude reinstall
untested.
The perms of /dev should fix themselves up automatically on reboot as
udev should be recreating the devices on the fly.
A
other than the fact that the system becomes vulnerable to attacks via my
internet connection, what is the problem with binaries with incorrect
permissions?
is there any simple way to enable 'su' for root?
