- Trying to enable a SysV init service results in an error:
+ SRU TEST CASE:
+ --------------
+ Trying to enable a SysV init service which does not have a corresponding systemd unit results in an error:
  
- # systemctl enable sysstat
- Synchronizing state for sysstat.service with sysvinit using update-rc.d...
- Executing /usr/sbin/update-rc.d sysstat defaults
- Executing /usr/sbin/update-rc.d sysstat enable
+ # systemctl enable pulseaudio
+ Synchronizing state for pulseaudio.service with sysvinit using update-rc.d...
+ Executing /usr/sbin/update-rc.d pulseaudio defaults
+ Executing /usr/sbin/update-rc.d pulseaudio enable
  Failed to execute operation: No such file or directory
  
- I expected the service to be enabled.
+ /etc/init.d/pulseaudio actually does get enabled (check
+ /etc/rc*/*pulse*), but the command fails with code 1 and you get that
+ error message. With the fix the command succeeds.
+ 
+ SRU Regression potential
+ ------------------------
+ Low, the modes for "sysv script + systemd unit" as well as "systemd unit only" already have automatic tests, and now this scenario ("sysv script only") has a test too. In the worst case this has the potential of completely breaking systemctl enable/disable, which can be worked around with changing symlinks manually, and isn't breaking the boot.
