Systemd boot is extremely "loud" with the quiet kernel parameter

Stitch · 2015-04-30 04:07:37

Systemd boot got really slow at some point.
It prints all the messages with all the green OK status. It is extremely slow, in fact, slower that any sequential boot 20 years ago. No errors though.
Kernel parameters are as per silent boot article with quiet and log level set appropriately.

Any help is appreciated. Maybe I can fiddle with some other systemd parameters? It does not look it parallelised at all.

What is in the journal? Blame? etc...

Not a Sysadmin issue, moving to NC.

Post the output of

cat /proc/cmdline

If this is not sys admin issue then I don't know what is....

I am sorry but I posted it in sys admin to avoid the exact questions: "What's in the journal?" Lots of output is in the journal as usual.
If there was anything significant to the issue I'd deferentially mentioned it. Nothing special there as far as I can see. No errors if that's what your are asking?
Is there anything specific do you want me to look at?

The same goes for blame. Nothing unusual, at least to my eye. 'NetworkManager-wait-online.service' takes 4 secs. This is the longest. Everything else in ms.
Regardless of the time per service spend, isn't it supposed to be in parallel and non-blocking fashion?
Every service is run sequentially. And the output is displayed on the screen. I suppose this is my problem.

As I mentioned in my original post, everything is as per silent boot article.
"quiet loglevel=3 vga=current rd.udev.log-priority=3"
Everything else is irrelevant.

Since you are asking why your boot is slow even if you think something is "irrelevant" you should post it all. Unexpected combinations of settings may not be visible to you and will definitely be invisible to everyone else without full details.

EDIT

Also, from earlier in your thread:

Post your: Blame.

See my edit to my above post, I edited at the same time as you posted, post your blame.

Stitch · 2015-04-30 08:52:58

I have to rephrase the original post.
Although booting is slow but it is not the most accented part of the question. Which is my fault not putting it correctly.
The major points are: Why is it sequential even for unrelated services when it should be parallel? Why is it spitting everything out on the screen when kernel parameter 'quiet' is present.
Solving the first might as well help the speed issue a bit.

For getting messages, try:

systemd.show_status=0

As a kernel line parameter.

For the rest of it still post your Blame as a starting point.

Edit: and try it with and without "quiet".

That did the trick with the messages. Thanks. I am wondering why quiet does not produce this effect?

As for the blame I will post it as soon as I am in front of the machine.

You're welcome. Do post your Blame when you can.

It looks like a network issue, try disabling the networkmanager service, reboot and see if that fixes your problem. If it does, investigate why networkmanager hangs
