Hello All,

I need a temporary directory in /run.

I'm going to create a foo.conf file in /etc/tmpfiles.d with the following content

How do I make sure that /run/bar is not defined in another .conf (in /usr/lib/tmpfiles.d or elsewhere) ?

Is there an alternative to grep ?

If one day I install a new package which defines /run/bar in its .conf, the conflict will be reported in the logs, but I must confess that I don't read the logs at each reboot.

So something will break (either my scripts or the package, I didn't read the doc enough to tell it), with possible loss of data or DOS.

Is there any naming convention that solves this problem ?

TIA for any help.

Does offer any insights?

No, the man page does not discuss conflicts.
This is a valid point.
In practice, the systemd-tmpfiles aborts all further activities when there is a duplicate.
And a duplicate might exist even in /etc/tmpfiles.d/systemd/system/ and (/usr)/lib/systemd/system/.
