small brain dump and more

As new RHEL 6 arrived, trying to do installation as minimal. Once done via anaconda standard click-next , I realized that no option for minimal installation left in cf file.

After small searching , regarding this bug RHEL6 docs: Add information on minimal platform installation via kickstart – all fixed, and kickstart is installing 222 packages and not 378

Memory used: 47 MB !!

NOTE: as yum is working ok, just wget is missing, and also my favorite midnight commander, Im including this in kickstart file also. Here it is

Kickstart for minimal installation of RHEL6 final:

1. at boot screen , press TAB and write additional parameter to command line for boot as on screenshot. –-eject parameter make automatic reboot after installation (not waiting for user input) – aaaah, not yet , need to find out ;(

• Here is file content:

• so, clean, minimal installation of RHEL 6 after reboot looks like this
• HTOP – Memoty 47 MB – TASKS 25 (still can disable auditd and postfix)
•  TOP –  MEMORY 123MB – TASKS 88

Screenshot from htop

Post install script is another story
