Hi!
TLDR:
How should the [Install] section for static systemd unit file look like?
Long:
Getting a lintian warning if using [Install] section.
I: qubes-whonix: systemd-service-file-missing-install-key
lib/systemd/system/qubes-whonix-redirect-9050.service
N:
N: The systemd service file does not contain a WantedBy= or
RequiredBy= key
N: in its [Install] section.
N:
N: Forgetting to add such a line (e.g. WantedBy=multi-user.target)
results
N: in the service file not being started by default.
N:
N: Refer to the systemd.unit(5) manual page for details.
N:
N: Severity: normal, Certainty: wild-guess
N:
N: Check: systemd, Type: binary
Should it be considered a lintian false positive?
Or do you suggest something like
[Install]
WantedBy=none.target
?
How to get rid of that output? (It will certainly generate a usability
issue, users being concerned about this.)
Setting up qubes-whonix (1:6.6-1) ...
qubes-whonix-redirect-9050.service is a disabled or a static unit, not
starting it.
In this case, I guess the systemd unit service file related to the
systemd unit socket file rightfully should not get a [Install] section
since the server gets started by systemd socket activation and has no
reason to be pulled in my a target such as multi-user.target.
"WantedBy=multi-user.target" even generates noise in journal, since no
socket was passed, systemd-socket-proxyd exiting non-zero and systemd
regarding the service as failed.
Example:
/lib/systemd/system/qubes-whonix-redirect-9050.socket
##########
[Unit]
Description=redirect 9050 to Whonix-Gateway in Qubes TemplateVM socket

After=qubes-sysinit.service
[Socket]

[Install]
WantedBy=sockets.target
##########

## Fix lintian warning.
