[clue-tech] RedHat/CentOS version 5

[Mike Staver]

In regards to questions about what breaks, nobody seems to specifically 
say.

After reading that, I'm kind of afraid to do it. Obviously I'll make 
backups, etc, etc.  The one thing I'm still having problems with is my 
password file. I can backup everything else on the system, but I had a 
problem a while back where I could try to unshadow the /etc/passwd file, 
and the process would never complete.  It would just hang, for days at a 
time if I would let it.  I suppose I could make all my users pick new 
passwords, but that would make people angry I think.  Also, I use RedHat 
based systems because I tend to use ColdFusion 7 MX on a lot of the 
linux systems I have. Think Macromedia/Adobe just support Suse and 
RedHat systems if I'm not mistaken.  I dislike Suse a great deal, so 
RedHat it is for me.
