Linux System Administration
     Linux system administration is a very broad topic, mainly because a system administrator's job seems to involve literally everything. This page will focus mainly on Redhat Enterprise Linux 6 (RHEL 6, or CentOS Linux for the time being) but a lot of the information will hopefully be universal to Linux, and even other UNIX flavors in general.

     Additionally this page is for my students in CIS 126DL Linux Operating System-Multi-User, and CIS 226AL (Internet Servers, Linux Flavor) at Mesa Community College, Az.

(Note: Extreme thanks to Bryan Feir of CRESTech in Ontario Canada. Without his willingness to spend 10 hours online walking me through the rebuild of the initrd.img files on BOTH the Redhat Install and Boot disks, we would not have been able to install to the Jazz cartridges and the course would have been dead long before we were able to purchase removable HD bays. Thank you again.)
