Both filesystems are ext3, although /dev/hdb is indeed rather full, so I'll
trim the waste from there:
$ df

/dev/mapper/VolGroup00-LogVol00

My apologies, I was hoping for some reason in your reasoning. Your
"subconscious" statements make no sense whatsoever, any way I consider
them.

Impersonating your wife is a hanging offence in some states.

Posting to a Linux newsgroup using Micro$loth Outlook Express is

Hey- it could be a lot worse: He knows what usenet is since he is
using a newsreader, he doesn't shove a binary signature into
an ascii newsgroup, he doesn't post anonymously, knows how
to bottom-post and he doesn't come in through Google.

not bad at all compared to some.
