Thanks for the guide, avx. I'm happily using zsh now with grml's config (however, you'll want to delete everything with "limit" in the config, as it produces a warning, and also "ls", because it calls the busybox with wrong parameters).

Oh and I also almost bricked the phone... good to have the recovery console installed I've then changed the shell back to /bin/sh in /etc/passwd

I recommend that you don't set the shell for any user by default. Let the user do this, if he thinks that he's ready.

I'll go with Char's solution to change the launcher. /bin/zsh can also be set in PuTTY as start command, in case anyone uses that too



EDIT: works great now! I've added some aliases, so I'll always have zsh instead of bash (you might need to customize that if you use gainroot, I don't):


/home/user/.zshrc.local

alias su="sudo su -c /bin/zsh"

/root/.zshrc.local

alias suu="su user -c /bin/zsh"
