[systemd-devel] [PATCH 0/3] Fix issues re: visibility of status messages

[Olivier Brunel]

Hi,

I'm running Arch Linux, have been using systemd-204, and recently tried the new
207 release, and I have been having some issues with it. One was that status
messages would just stop at some point near the end of the boot process, and
also that I wouldn't get any during a shutdown/reboot.

It might be useful to note that I don't start a getty on tty1, which is why I
expect to see all status messages until default target is reached, even after
the getty/login has been started (which happens on tty2).

After looking into it, I came up with the following patches to fix the issue.
The reason status messages would stop was that the getty was started, and
systemd then stopped using the console to avoid "collisions" w/ gettys.

However, as I said I don't have a getty started on tty1 so for me that is a bug,
as there's no reason not to keep printing status messages on tty1.

The lack of messages on shutdown/reboot was also linked to this, because if
no_console_output was set to true during boot, it'd stay there and prevent
messages to show up on shutdown.

To fix this (in the event it was set to true on boot) a patch simply resets it
to false on job_shutdown_magic(), but I'm not exactly sure if that's the right
way to do this.


FYI I should add that in a similar setup as the one I described, this will not
be enough to keep messages on tty1, since fsck's units are now RemainAfterExit
(see https://bugs.freedesktop.org/show_bug.cgi?id=66784), which means they're
seen by systemd as "owning" the console (as far as outputing messages there is
concerned I mean), and it will therefore stop printing status messages.

I'm not sure you want to "fix" this, as it might be only a cosmetic issue for a
small usecase hence not worth the trouble, so I've simply "undone" it using a
.conf file on my end, figured I should mention it though.
