autofs-5.0.6 - fix remount of multi mount
|
|
|
|
From: Ian Kent <ikent@redhat.com>
|
|
|
|
Went accessing a multi-mount only the the offsets that need to be mounted
|
|
are mounted. But when re-mounting multi-mounts during a restart we need to
|
|
also traverse into existing mounts and re-connect to triggers mounted within
|
|
them.
