Messieurs

Lockwood and Boland,

First, I'd like to thank you both for your help.

Second, A bit of my own foolishness.

    When I tried to recover from my error I:
        1. booted into 'recovery' mode, 2nd item on the default LILO menu.
        2. selected the last item on the list. (This mounts the / as
    read only.)

    When I took the time to actually read ALL of the choices on that
    list I found that the 2nd or 3rd choice was to reboot and mount / as
    read/write.

After selecting that option I ran 3 of the 4 suggestions you mentioned
above.

I redirected the results to a file the contents of which you can see below.

After each command had run I rebooted to the GUI. Though I could not log
in after the first 2 commands I was able to after the 3rd. Everything
now seems to be as it was before I cause this headache for myself.

That being said it was a good experience, remembering/relearning some of
what I had forgot from so long ago.

Thanks again for you help!

P.S. You may notice that I had to prepend the filenames with ./ as the
system could not find them otherwise.
