When starting autofs when there are active mounts due to in use
|
|
|
9a499a |
mounts from a previous shutdown, and a mount entry has offsets
|
|
|
9a499a |
that are within an autofs mount, the mount point directories are
|
|
|
9a499a |
incorrectly marked as not created by us when re-connecting to the
|
|
|
9a499a |
mount so they are not removed at expire.
|
|
|
9a499a |
|
|
|
9a499a |
Since the base autofs mount directory needs to be empty for mounts
|
|
|
9a499a |
to be triggered these directories disable automounting for the mount.
