[Bug 1945873] Re: vt.handoff=7 ~broken on VM

[Mason Loring Bliss]

** Description changed:

- 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.)

Bug description:
  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.
