Can't start the service with systemd

[Ronny Trommer]

I've installed softflowd with apt install softflowd. If you try to enable and start with systemctl enable softflowd you get the following message:

Synchronizing state of softflowd.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable softflowd
Created symlink /etc/systemd/system/multi-user.target.wants/softflowd.service → /lib/systemd/system/softflowd.service.

if you look into the softflowd.service file, it just calls /bin/true for start and stop. When you use the multi-instance version the configuration file doesn't match to the systemd unit.

1.) the path is /usr/bin/softflowd instead of /usr/sbin/softflowd. It seems this is changed between 0.9.9-3 and 1.0.0-1 and was not updated. Additionally, the variables for $interface and $options are lowercase in the systemd unit file and upper case in the configuration file. After fixing this, creating a configuration file in /etc/softflowd/default.conf, the service can be enabled and started in ubuntu:eoan with systemctl enable | start softflowd@default.
