also i give you a procedure to test a service without touching your actual trees and mostly your scandir(meaning PID1).
create and launch a new scandir
# 66-scandir -l /run/scandir -cu
This command grabs your terminal. So open an another one, then create a new tree
# 66-tree -cn test
Enable your service, and start it (note the -l option)
# 66-enable -l /run/scandir -S uksmd
Check it
# 66-intree -zg uksmd
# 66-inservice -zg uksmd
To stop your scandir and remove it
# 66-scanctl -l /run/scandir stop # this stop the scandir
# 66-scandir -l /run/scandir -r # this remove it entirely from your system
The exact same procedure can be made as regular user if you want to test user services.
Enjoy the power of 66 :p.
Note: 66-start and 66-stop have the -l option. Do not forget to pass it to handle the correct live directory.
