Comment 0 for bug 1945873

In an install made with 21.10 beta, the default settings add vt.handoff=7
to the primary kernel command line in /boot/grub/grub.cfg. The effect of
this is that the virtual console is somewhat broken during boot. Prompts
for LUKS passphrases are hidden, and once the system is done booting, getty
prompts do not show until the user navigates to another virtual console.
(This isn't possible until the system is booted, meaning it's not a
mitigation for accessing LUKS prompt. For that, a user can hit escape and
be presented with a partially-functional LUKS prompt.)

Attached is an example of a getty prompt not showing. This is after hitting
ESC to get a LUKS prompt so that disks could be unlocked, so that doesn't
help later boot.

The system in this case is a debootstrap-installed ZFS-on-root with an ext4
MD-RAID1 /boot.
