Upps. Corrected, thanks.

Thanks.

It seems to work on the "last tty", but on the other ones I'm getting:

/etc/zsh/zshrc:cd:22: no such file or directory: /home/LOGIN
$ echo $LOGNAME
LOGIN
$ whoami
grml
$ id -un
grml

I can't find the reason for this behaviour (inittab entries are the
same and behaviour seems to change when booting system serveral
times), but using `id -un` instead of $LOGNAME seems to fix it.

Ah, ok - I see what you mean. Yes, seems to be related.

Oh, my thinking was too complicated. :)
Thanks Bart, works like a charme!
