# GRUB on the instance's host at home (ADR 0039, D20), as /etc/default/grub.d/halkyon.cfg:

# its menu shown for 5 seconds, so that at the iMac the way back (grub-dracut-fallback)
|
|
# can be chosen, and the boot in text, without a splash: no desktop, and the
|
|
# passphrase's prompt is plain on the screen as over SSH. The console blanks after
|
|
# 60 seconds without a key (consoleblank), which powers the panel down, backlight and
|
|
# all; a key wakes it, and the prompt at boot is shown until then.
