Bug 1223617

Hello!

Where does the file /etc/tmpfiles.d/var.conf come from?

Can you share its contents?

It is expected to get the duplicate warning in the log if multiple files specify the same path. See CONFIGURATION DIRECTORIES AND PRECEDENCE section of 'man tmpfiles.d'.

If you want to override some settings from a system supplied file found under  
/usr/lib/tmpfiles.d/ then you have to create a file with the same name under /etc/tmpfiles.d/ and in this way the on under /usr/lib/tmpfiles.d/ will be ignored.

Hello, any development on this issue or we can consider it solved?

My IDP login isn't working and no one responds to emails sent to the bugzilla admin email address. I just had to create another account using another email address.

I created /etc/tmpfiles.d/var/conf and it contains

Below is the output from the opensuse box before reboot and then after reboot. The files defined in the /etc/tmpfiles.d/var.conf do not have the permissions defined.

I wasn't reading carefully enough and didn't realize the config files had to be the same name as the original to overwrite. I did an initial test and it seems to be working. Do we know the logic behind the decision to force the file name to match for an override vs creating your own configuration file and matching off the contents?

I don't know the exact reasons, but it's the upstream behaviour.

Closing as invalid, as it's the expected behaviour.
