Hi, when running "systemctl enable multipathd.service", systemd also wants to enable multipathd.socket due to the following line in multipathd.service: > [Install] > ... > Also=multipathd.socket At least on systems running systemd 235, this leads to the following error: > The unit files have no installation config (WantedBy, RequiredBy, Also, Alias > settings in the [Install] section, and DefaultInstance for template units). > This means they are not meant to be enabled using systemctl. > Possible reasons for having this kind of units are: > 1) A unit may be statically enabled by being symlinked from another unit's > .wants/ or .requires/ directory. > 2) A unit's purpose may be to act as a helper for some other unit which has > a requirement dependency on it. > 3) A unit may be started when needed via activation (socket, path, timer, > D-Bus, udev, scripted systemctl call, ...). > 4) In case of template units, the unit is meant to be enabled with some > instance name specified. This error occurs because multipathd.socket is missing an [Install] section and in particular a "WantedBy" line, so systemd does not know how to enable it. The section was removed in commit 62ef3766d9472f2122bc1dbd1e685f3e914b626b a few years ago. I guess there are two options to fix this: either removing the "Also" line in multipathd.service so that multipathd.socket is not enabled as well, or adding back an [Install] section to multipathd.socket.
