I also tried to explicitly write out the specific sv folders in the /usr/share/runit/ folder.
I still get the same error and the /var/log/iso-snapshot.log file was never created.
This is totally unexpected behaviour (I have tested this setting on a live system & it succesfully produced a test iso – however it still generated the extra service folders so no need for it).
On the other hand I have found the cause of the issue & I’ll post an update soon.
