Hi all,

When I am installing I use kickstart and have a line like:
    repo --name=Updates 
and that works great for installing the OS.

After that the machine reboots and I have it automatically go into 
additional installations running scripts.
These installations do "yum install XXX".
However, its no longer using my above repo its using the mirrorlist (as 

My questions are :

1) I dont see a way in yum to say "use this repo to install", is there a 
way to point to my server in the office
and dont do the mirrorlist.

2) Do I just drop a file called CentOS-office in the /etc/yum.repos.d 
that looks like this and it will be used first instead of the mirrorlist:

name=CentOS-$releasever - Base

#released updates
name=CentOS-$releasever - Updates

I dont want to mess anything up and I want additional package installs 
in the office to go faster
in the office. I can remove the file when I am done installing.

Is there a better way or is this the way to do it?
