Subject: [PATCH] refactor(squash): don't record mount points in text file
|
||
|
|
|
||
|
|
The squasn mount points are recorded in text file so later clean up
|
||
|
|
script can umount them, this is not needed, the mount points are fixed
|
||
|
|
so just detect the umount by hardcoded pattern.
|
||
|
|
|
||
|
|
(cherry picked from commit bdd194bb8c0427921b87b4dce16c05e18e0c2fb0)
|
||
|
|
|
||
|
