Description Sergio Rubio 2012-09-05 13:47:57 UTC

Description of problem:

cloud-final.service needs StandardOutput=syslog+console so that final-message gets printed to the console while booting. The following patch did the trick for me:

After applying the patch the following cloud-init boot message gets printed to the console after booting:

cloud-init-cfg[792]: cloud-init boot finished at Wed, 05 Sep 2012 13:37:54 +0000. Up 5.85 seconds

Description :
Cloud-init is a set of init scripts for cloud instances.  Cloud instances
need special scripts to run during initialization to retrieve and install
ssh keys and to let the user run various scripts.

Comment 1 Garrett Holmstrom 2012-09-14 02:29:02 UTC

At first glance "syslog+console" doesn't seem like the right setting for this, given that cloud-init already logs to /var/log/cloud-init.log, so I'm leaning toward making it just "tty" instead.  But then again perhaps it would make more sense to use "syslog+console", tweak cloud-init's own logging configuration so it logs only to syslog, and then ensure that the included rsyslog config file works properly.

Would the latter break the way you're using cloud-init?

Comment 2 Sergio Rubio 2012-09-14 09:13:18 UTC

Hey Garret, thanks for the input.

It won't break anything for me (I can easily patch it in any case).

The thing is that being able to see cloud-init messages while booting is a good thing IMO. You can easily fetch console output from AWS and OpenStack (nova console-log, ec2-get-console-output) and debug instance boot, monitor boot time, etc.

I'd say it's a minor issue but a handy feature to have. The bug is about the cloud-final systemd service, but every cloud-init module that wants to print something while booting should be able to do that I guess.

What do you think?

Thanks!
