I just tested, and when selecting grub the command line in the final system
will contain 'quiet' even when using expert mode (which boots without it,
double-checked in a console during install).
Also, systemd-boot-installer won't pick-up the 'quiet' even when added manually
to the command line when booting the installer (systemd-boot /does/
pick-up 'quiet'
from the current system when installed in an existing system).
It seems to me there are different mechanisms used during install and on manual
installation of systemd-boot, because the former ends up with
/etc/kernel/cmdline
(containing only 'root=UUID=<UUID>'), but the latter doesn't.
Kind regards,
Andrei
