This week I was "on-site" for a PowerCARE Linux on POWER engagement. Always new things to learn - and because it had been a few months - I also learned a few things that I will never forget again - e.g., to open the firewall port for RMC so that RSCT can communicate with the HMC.

I am working on a presentation - more for customers - but also a "cheat sheet" that I will share.

And I wish I could claim more originality for some of the material I have developed the last two weeks. Unfortunate for my ego - many people, well at least one! - thought similiar thoughts 10 years ago.

The one from 10 years ago? Very nice description of the LINUX boot phases: see Inside the Linux boot process
