Not at all, I just don't want to lose the shell history.

Yes, but that would considerably increase SSD wear (see other mail
thread); so I do it manually once in a while.

Actually, what's really strange is that the shell should not be
started at all in this situation: The display only ever fails
when powering on; once it works it keeps working. In that
situation I don't log in because I can't see anything. I'm not
even sure getty starts up at all. So, why does any zsh run at
all if I can't even log in?
Ciao
