Package: initramfs-tools
Version: 0.136
Severity: minor
Dear kernel team,
I'm using Debian on an arm64 chromebook, and not setting "console=tty1"
in the kernel command line results in a number of weird behaviours
related to the initramfs.
During an ordinary boot, plymouth doesn't show the futureprototype boot
splash. Instead, it shows the init log; but pressing ESC does switch to
plymouth (but with what I'm assuming is the text theme instead).
If I use "break" (even "break=init") in the kernel command line, I don't
see an initramfs shell prompt and the keyboard does nothing. If plymouth
is installed, I see the "Spawning shell within the initramfs" message
but rest is the same (plymouth quits in it's panic hook).
When I'm trying to boot from an encrypted root (different installation),
I don't see the "Please unlock disk" cryptsetup prompt and can't type a
passphrase; unless plymouth is installed.
I'm able to boot the encrypted system as a QEMU virtual machine and I
get similar behaviour there, no messages or prompts are printed to the
graphical console and instead all go to the serial console. However
having plymouth doesn't make the cryptsetup prompt ask in the graphical
console in the virtual machine.
All these are fixed by simply adding "console=tty1" to the command line,
is that something a user is supposed to do manually (e.g. GRUB configs)?
Should the initramfs (or maybe the kernel itself) be detecting when
graphics are working and automatically switch outputs/prompts to that? I
want to work on this, what would be the best way to proceed?
