Hi Scott,

I have some issues and questions:
For the OS install, since you specify what packages to add/remove, why
not just include your kickstart.ks file with instructions on how to
create a kickstart disk?  This avoids the unresolved dependencies
problem.

Your instruction say to remove sendmail in the initial set up, then,
after your reboot, you remove sendmail again.  What happened?

You add users by modifying /etc/passwd with no updates to /etc/shadow. 
Methinks this is not the optimal solution.  Should they not be kept in
sync?  I was taught they must be updated together.  Also, from a
security perspective, direct edits to config files and databases is a
bad idea (see Clark-Wilson security model), and I have seen many botched
production changes because of this.  I realize there are no tools to do
most of what you do in your how-to, but directly editing /etc/passwd?  I
had a tech lead that personally promised corrective action/termination
to every engineer that edited /etc/passwd directly.

You copy the /etc/time zone file to /var/spool/postfix/etc/localtime -
wouldn't making a symlink be better?


Other than that (and the grammar - but that's a George issue), the
instructions are very straight-forward and obvious.  Good job.

George

What does that tell you if your project is ahead of schedule and under
