Package: init-system-helpers Version: master branch Hello,
Using "deb-systemd-helper is-enabled xxx.servce" answers "disabled" even if the service is enabled. To check if a service is enabled, the script gets all (closure) dependent services (via Wantedby, RequiredBy, Also, Alias, ...) and checks if the filesystem link is found in /etc/systemd/system/xxx.wants. Unfortunately this does not work, if a dependent (also) service is not enabled. I know, it is strange to have dependent services not enabled. In systemd there are several dependencies with different meanings. https://www.freedesktop.org/software/systemd/man/latest/systemd.unit.html Especially the "Also" option is going only in one directrection. If the service containing the "Also" is enabled, the services under "Also" are enabled, too. But not the other way around. The services under "Also" are not needed. Example: I saw this with "systemd-networkd.service", which contains "Also=systemd-network-generator.service" and this contains "WantedBy=sysinit.target". The "deb-systemd-helper" script checks if "systemd-network-generator.service" is in "etc/systemd/system/sysinit.target.wants/" which is not the case, because "systemd-network-generator" is not enabled. The "systemctl is-enabled systemd-networkd.service" returns "enabled" as expected. Of course "systemd-network-generator" can be enabled, but it is not needed to have "systemd-networkd.service". Thanks for taking the time to think about this! Greetings ... Marco
