Here is the question: lets say you fix the initial problem and CAN log
in as root. What next? You have a few hundred files with the wrong
permission.

Q: How do you fix this? A: with great pains!

On an average unix system, you can access the data or configuration by
using a live cd or similar, then back that up. Now that you have the
important data like the output of 'dpkg --get-selections´, you now know
what packages to install when you reformat the partition! So you do a
base install, use 'dpkg --set-selections', do the other bits to install
the rest of the packages, and in about 1/2 a day, you can be back to a
reasonable state.

The other way is to fiddle with a few hundred files until you get an
only mildly broken system. At least that is the way I look at it, YMMV.

But I would still like to get a list of the normal /dev perm's. Keep in mind
that my system, so far ;) , seems to be functioning normally, except I can't
do 'su'. Another consideration is that I'm thinking of getting new hardware
and would as soon put off the systems work until then.
