[NBLUG/talk] Moving permissions

[Todd Cary]

Dustin -

Making very good sense.  Now I have to check to see how big

/home
/etc
/usr

are so I can tell if they will fit on a CD or DVD.

DB data I consider a different animal.

With my Windoze system (how I earn my living ), I never worry about 
losing source code; my BIGGEST fear is having to reinstall the OS and 
the days it will take to get everything back in order (though my Ghost 
images help ease the worrying a little).  This is what I want to avoid 
with Linux.

Many thanks....

Todd
