The /usr/lib/icinga2/prepare-dirs script does not seem to ensure /var/cache/icinga2 is present and writable. This causes a freshly installed icinga2 to crash out of the box on my end:

-- Unit icinga2.service has begun starting up.

-- Subject: Unit icinga2.service has failed

I have fixed the issue by appending the following lines to prepare-dirs:

ICINGA2_CACHE_DIR=$ICINGA2_STATE_DIR/cache/icinga2
mkdir -p $ICINGA2_CACHE_DIR
chown $ICINGA2_USER:$ICINGA2_GROUP $ICINGA2_CACHE_DIR
chmod 750 $ICINGA2_CACHE_DIR

Icinga2 works correctly on my end with these changes present.

Ah, Gentoo. That clears it up a little. I suspected that the RPM/Debian packages weren't properly preparing those directories.

@mthode
Can you please fix the Gentoo package in order to provide those dirs upon "package install" already similar to how the other distributions behave. Thanks.

I could do that, but that directory is supposed to be able to be deleted. Everything in /var/cache is.

http://www.pathname.com/fhs/2.2/fhs-5.5.html

/var/cache is intended for cached data from applications. Such data is locally generated as a result of time-consuming I/O or calculation. The application must be able to regenerate or restore the data. Unlike /var/spool, the cached files can be deleted without data loss. The data must remain valid between invocations of the application and rebooting the system.

This is something that should be done at service start.

• Subject changed from Gentoo: /var/cache/icinga2 not created upon package install to _/usr/lib/icinga2/prepare-dirs does not create /var/cache/icinga2 _
• Assigned to deleted mthode

This is probably something which should be done in the prepare-dirs script.

[ekohl]

The best solution would be to ship a tmpfiles.d file. Locally I've created /etc/tmpfiles.d/icinga2.conf with d /var/cache/icinga2 0750 icinga icinga as content to ensure the directory exists.

I implemented the simple fix in the references PR by extending the current method using the code suggested by the author.
