Is it possible to run a command like "su - root -c script" in post-install actions when using text mode installation? I tried and the installer gives the error I display on attempt to run this command. I assume that maybe it is related to the fact that this command needs the user to enter a password. If this is the case, what will be the correct way to handle it in text mode installation?
Another question related to this, is there a way to force the installer to go back to the previous step in case that user/password is invalid?
