Want to compile small kernel.

As a first step, as I cannot yet compose the working initrd, I will use the existing pmagic iso which is 2.6.34 for i686 and replace kernel image.

As for package dependencies/toolchain - too many, search for error or ask me in comments.

$ git clone -v git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
$ git branch v2.6.34.1
Then patch something:
$ cd linux-stable ; patch -p0 < patch.diff

Patch is below:

Recently I found tmux. This is a best thing if you manage to work with your server in ssh console on a bad connection or from time to time and would like to save the entire context of what you are doing. For example, you compile kernel and went take a coffee, then back and connection dropped. If you used tmux simply attach to session:

$ tmux a

Need (like me) several consoles? (It's for sure more verbose than to have nohup or Ctrl-z; bg)

<Ctrl-b> , enter "new" <Enter>

For a list of sessions:

<Ctrl-b> , s

(then select from stable list - meaning you remember that for example your unprivileged session is always third one, and first two is sudoed root ones). Example (selected 2nd):

(0) + 0: 1 windows
(1) + 2: 1 windows
(2) + 3: 1 windows (attached)

The only not a good (yet) thing is scroll up as it needs 2 more keys:

<Ctrl-b>, [, then <PgUp/Down> or Arrows

Have fun!
