Guys/Gals,

Forgive me if this is a very noobish question, but I'm getting a bit lost here. I've got a Virtualbox guest environment which was working fine, and following the news item about Gnome 3.8 stabilization I migrated to systemd.

Things seem to work OK, except that I'm getting very odd logging behaviour. If, for example, I mount my /boot partition I get the following:

Code:
localhost ~ # mount /boot
[ 1406.986157] EXT4-fs (sda1): mounting ext2 file system using the ext4 subsystem
[ 1407.008946] EXT4-fs (sda1): mounted filesystem without journal. Opts: (null)


Why are these messages being logged to the console?

linux/.config:
CONFIG_DEFAULT_MESSAGE_LOGLEVEL=1

Thanks ulenrich,

Maybe I'm missing something; if I change
Code:
CONFIG_DEFAULT_MESSAGE_LOGLEVEL
from 4 to 1 that'll just reduce the amount of information being logged rather than solving the issue of the log information being immediately written to the console?

Cheers

Well, that's another question :)

Perhaps your /boot was created with little options due to /etc/mke2fs.conf.
You can specify options in /etc/fstab following the /boot created conditions:
tune2fs -l /dev/sda1

I think we're talking cross purposes; I'm getting a large number of messages written directly to tty0 when I'm working on that console. I was not getting this behaviour pre-systemd, and was simply using the example of mounting my boot partition which is one of many operations that cause this behaviour.

Look at files shown when

grep -eDefaultStandard -eLog -eForward /etc/systemd/*.conf

OK; that gives me:

Code:
/etc/systemd/journald.conf:#ForwardToSyslog=no
/etc/systemd/journald.conf:#ForwardToKMsg=no
/etc/systemd/journald.conf:#ForwardToConsole=no
/etc/systemd/logind.conf:[Login]
/etc/systemd/system.conf:#LogLevel=info
/etc/systemd/system.conf:#LogTarget=journal-or-kmsg
/etc/systemd/system.conf:#LogColor=yes
/etc/systemd/system.conf:#LogLocation=no
/etc/systemd/system.conf:#DefaultStandardOutput=journal
/etc/systemd/system.conf:#DefaultStandardError=inherit
/etc/systemd/user.conf:#LogLevel=info
/etc/systemd/user.conf:#LogTarget=console
/etc/systemd/user.conf:#LogColor=yes
/etc/systemd/user.conf:#LogLocation=no
/etc/systemd/user.conf:#DefaultStandardOutput=inherit
/etc/systemd/user.conf:#DefaultStandardError=inherit


As you'll see I've not touched any of the systemd settings.

If it helps make things clearer, I've captured a video of what's happening:

The comments show defaults, how about LogTarget=journal in both files?
Play with it, experiment! I don't think reasonable changes will harm:
man systemd-system.conf
man journald.conf
