Hi.
I was looking at how dynamic users are implemented and noticed that instances
seem to
share one dynamic user within their service. In the example below, I have an
attached
portable service with StateDirectory=derp-%i
# ls -dn /var/lib/private/derp-{foo,bar}
drwxr-xr-x 2 64000 64000 4096 Sep 2 17:59 /var/lib/private/derp-bar/
drwxr-xr-x 2 63000 63000 4096 Sep 2 17:59 /var/lib/private/derp-foo/
# systemctl start f30-derp@{foo,bar}
# ls -dn /var/lib/private/derp-{foo,bar}
drwxr-xr-x 2 63000 63000 4096 Sep 2 17:59 /var/lib/private/derp-bar/
drwxr-xr-x 2 63000 63000 4096 Sep 2 17:59 /var/lib/private/derp-foo/
# ls -l /run/systemd/dynamic-uid/
total 4
-rw------- 1 root root 9 Sep 2 18:12 63000
lrwxrwxrwx 1 root root 8 Sep 2 18:12 direct:63000 -> f30-derp
lrwxrwxrwx 1 root root 5 Sep 2 18:12 direct:f30-derp -> 63000
Normally the state directories are created under the same owner, I set
different owners
explicitly to see that the second instance's directory is chowned.
I guess I'm wondering if this behaviour is intentional? I found it surprising
but that
might just be me.
