[SOLVED] How to make grub2 show only [FAIL] messages during boot?

bdantas · 2014-07-24 11:28:40

How do I make grub2 be more quiet than "quiet"?

With "quiet" in the kernel command line, I would expect it to display only [FAIL] messages. However, what actually happens is that all boot status messages get printed to the console screen starting with a [FAIL] (i.e., even if only one thing fails, the boot process prints that failure and all the [OK]'s that follow).

(I am trying to recreate the old /var/log/boot but it would be simpler if I didn't have to deal with the scrollback buffer. See here: https://bbs.archlinux.org/viewtopic.php … 1#p1439361)

Have you tried https://bbs.archlinux.org/viewtopic.php … 6#p1439196 ?

I just did thanks to your tip. Unfortunately, now it does not even show my one [FAIL]--no boot status messages at all.

I also tried "systemd.show_status=1" for good measure but, as expected, it shows all the [FAIL] and [OK] messages from the beginning (i.e., behavior of "quiet" + "systemd.show_status=1" is the same as having neither parameter).

Does 'systemctl --failed' show the [FAIL]ed units?

bdantas · 2014-07-24 13:28:24

It does not. Among "systemctl --failed," "sudo systemctl --failed," "journalctl -b -p err," and "sudo journalctl -b -p err" only the last one mentions the [FAIL]ed unit.

Have you tried 'systemd.show_status=auto'?

systemd.show_status=
           Takes a boolean argument or the constant auto. If true, shows terse service status updates on the
           console during bootup.  auto behaves like false until a service fails or there is a significant delay
           in boot. Defaults to true, unless quiet is passed as kernel command line option in which case it
           defaults to auto.

Just tried it. It seems that's the default behavior, as the output is identical to just having "quiet" (i.e., with "quiet" + "systemd.show_status=auto" there are no boot status messages until [FAIL] shows up, but then it prints all the [OK]'s that follow).

I am starting to get a sinking feeling that what I am looking for is not possible.

It would be nice to at least get a clarification if that's the intended behavior, or is it a bug.

bdantas · 2014-07-24 14:16:03

I agree, but I wouldn't know who or where to ask.

See http://www.freedesktop.org/wiki/Software/systemd/
The quickest might be asking about this on IRC.

I asked systemd's Lennart Poettering by email: "Is it possible to display only [FAIL]ed units during boot?"

His answer: "No, we currently don't have such a mode. But I think this would be quite useful, so I have added this to the TODO list now!"

Is it http://cgit.freedesktop.org/systemd/sys … 490ec8ae1c ?

bdantas · 2014-08-15 01:32:37

Looks about right

Since this is an upstream issue, I'll mark as solved.
