So my employer has been nice enough to send to me to the new RedHat RHEL 6 certification track. I started this week taking the RHCSA RHEL6 certification class. This is the first certification that is now required before you can take the new RHCE exam.

Now I have been RedHat certified for years, the first certificate I got from them was the RHCT (RHEL3) back on 2004, they have made a lot of changes to RedHat over the years and the new two part certification program is nice example of a maturing certification.

I was pleasantly surprised to see all the changes in RHEL6.

• New init script based on upstart
• New cron process anacron
• New disk encryption program LUKS
• New logging process Rsyslog
• Better implementation of SE Linux
• OpenSSH now allows Match directive for chroot jail

I’m looking forward to CentOS 6 which is due out shortly so I can start implementing more of these changes for my customers.
