[ILUG] Backing up user accounts

[Tim Kiely]

I'll be changing distributions on a box that I have from redhat 6.2 to suse 
7.0 and I was wondering exactly what files I need to make copies of to be 
able to backup user accounts passwords, groups etc? and what I need to do 
to get them recognized on the new distribution? Is it simply a case of 
copying the files onto the correct locations or are there more sinister 
forces at work that need to be sorted out.
