[PATCH] systemd-systemctl: Add support for UpheldBy fields in [Install] section

[PATCH] systemd-systemctl: Add support for UpheldBy fields in [Install] section

[Torben Hohn via B4 Relay]

From: Torben Hohn <torben.hohn@bruker.com>

UpheldBy generates *.upholds links in the same way WantedBy generates
*.wants links, when systemctl enable is executed. This feature is needed
to have a service restart, when a dependency restarts, and
the service is stopped via BindsTo= for example.

Call self._process_deps() with appropriate parameters to support UpheldBy.

Hi Torben,

Thanks for your patch.

Can you confirm this is targeting the master branch? It looks like this
file was removed last year:

Thanks,
