Show messages on the boot screen: For example if a partition can't get mounted.

/kind feature

Describe the solution you'd like

There was an invalid UUID in the /etc/fstab file.

The machine did not boot, and we saw (when connecting to the hcloud server):

...
Press enter for maintenance (or press Control-D to continue)

But we did not see an error message indicating that mounting /boot/efi failed.

The next time I want to see the root cause on the screen, so that I find the issue earlier.

How can we configure that?

---

Grub

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash debug verbose"

Remove quiet and splash.

---

Systemd

/etc/systemd/journald.conf
ForwardToConsole=yes

I think this is still valid and easy to implement.
