Subject: [PATCH] 99squash: Only start the cleaner on switch-root
|
|
|
e83cdd |
|
|
|
e83cdd |
Currently it starts the cleaner early and do the clean up job if switch
|
|
|
e83cdd |
root is called. It's better to just start the service only on switch
|
|
|
e83cdd |
root to avoid any risk of service dependency failure and make is
|
|
|
e83cdd |
simpler.
