Add another option for debugging instead. Lots of users have been
complaining about this default behaviour.
This patch also cleans up the EFI bootloader entries in the ISO.
Allow password login to the installation this allows doing remote installation
via SSH. All that need to be done on the local machine is:
1. Boot from the installation media
2. Set a password with passwd
3. Enable SSH with systemctl start sshd
It is safe as root doesn't have a password by default
and SSH is disabled by default.
Fixes#20718
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
