3way gentoo

January 10th, 2009 Comments off

As I’m currently in process of installation gentoo 2008.0, I have learned few things:

  1. do not believe that Your’s system will work after update
  2. try to have backup boot medium like live cd or live usb stick
  3. have your home on separate partition or maintain a backup of it

As my OpenSuSE box beaked down on system update I have thought about going back to Gentoo. This was crucial step as I was really interested to have system build to satisfy my needs.
Gentoo is sort of such systems, it allows full customization of OS. For me it was the only choose, other systems take back the control of the system.

Currently I’m working on 3way Gentoo, which will allow users to safely update their system without loosing current working set of applications.

3way means that in basic configuration the system will be working on 3 system directories, one for compilation, one for system and one for backup. This way (one of 3) user will have always working OS. it is easily possible to make it 2 or 5 way process, as only first two steps are necessary, rest of them is only backup of the working tree.

I should have some results on this topic in next week.

dmraid activation in gentoo kernel

January 7th, 2009 Comments off

Even gentoo handbook says that good build kernel should work without initrd there are some cases that require it, that’s my case. I’m using build in raid from my motherboard, it contains intel ICH9 chipset, this is no true hardware raid, to work it requires software to be run. I have compiled my kernel with all required switches, but it was not seeing my root partition on raid device, so I have run this command

emerge genkernel; genkernel --dmraid ramdisk

This allowed me to boot my manually compiled kernel to run, just added generated initrd to /boot/grub/menu.lst, not sure if this was needed but I have also added option dodmraid to kernel in the same file.
