rd.break=cmdline broken

rd.break=cmdline broken

[WANG Chao]

Hi, Harald

I find that rd.break=cmdline will cause a dead lock of service
dependencies.

dracut-cmdline.service:
[..]
Before=systemd-vconsole-setup.service

dracut-emergency.service:
[..]
After=systemd-vconsole-setup.service
Wants=systemd-vconsole-setup.service

So it appears to be a dead lock between systemd-vconsole-setup.service
and dracut-cmdline.service if we issue dracut-emergency.service with
rd.break=cmdline.

Because vconsole.conf is generated under cmdline hook, so simply remove
'Before=systemd-vconsole-setup.service' wouldn't be a decent solution.

Wondering if you have any idea how to fix it.

Thanks,
WANG Chao

We/I should either make the vconsole.conf cmdline parsing script a generator and
be moved out of the cmdline hook; or more likely remove the deprecated,
following kernel command line parameters, when using systemd:

- KEYTABLE
- SYSFONT
- CONTRANS
- UNIMAP
- KEYMAP
- FONT
- FONT_MAP
- FONT_UNIMAP
- UNICODE
- EXT_KEYMAP
- LANG
- LC_ALL

and only accept vconsole.* and locale.* parameters, which are handled by systemd
out of the box.
