Sokets and RuntimeDir with correct owner and mode

[arthur-s]

I have an issue with sockets and RuntimeDir.
veronica.socket:

[Socket]
ListenStream=/run/uwsgi/veronica.sock
SocketUser=arthur
SocketGroup=admins
SocketMode=0660

[Install]
WantedBy=sockets.target

veronica.service:

[Service]
PermissionsStartOnly=True
User=arthur
Group=admins
RuntimeDirectory=uwsgi
RuntimeDirectoryMode=0755
RuntimeDirectoryPreserve=always
ExecStart=some-command
Restart=always
KillSignal=SIGQUIT
Type=notify
StandardError=syslog
NotifyAccess=all

[Install]
WantedBy=multi-user.target

Now, after reloading systemctl daemon-reload, I start socket:

# systemctl start veronica.socket
# ls -al /run/uwsgi
drwxr-xr-x.  2 root    root   60 апр  1 07:20 .
drwxr-xr-x. 26 root    root  740 апр  1 07:20 ..
srw-rw----.  1 arthur admins   0 апр  1 07:20 veronica.sock

note, that RuntimeDir was created with owner root:root
and start service:

# systemctl start veronica.service
(it fails).
# ls -al /run/uwsgi                     
drwxr-xr-x.  2 arthur admins  60 апр  1 07:22 .
drwxr-xr-x. 26 root    root  740 апр  1 07:22 ..
-rw-r--r--.  1 arthur admins   6 апр  1 07:22 veronica.pid

You can see, that when I started service, RuntimeDir was deleted and created with owner arthur:admins.
I expect, that when I create socket, RuntimeDir must be created with owner and mode, taken from veronica.service, and then when I start service, runtime dir must contain veronica.socket and veronica.pid files

[arthur-s]

Sorry guys, problem was solved by using another dir for socket:
[Socket]
ListenStream=/run/uwsgi-sockets/veronica.sock

and for service:
[Service]
RuntimeDirectory=uwsgi

Now it works. Issue can be closed I think.

Yeah, the RuntimeDirectory lifetime is tied to the service, so you shouldn't use it for things that could predate or outlive the service.

I'll close the issue now.

I just ran into this as well, opened #32503 so hopefully less people will run into it in the future.
