When swicthing to use the mnt_list to track mounts for expire, if the
|
|
|
29d2b9 |
amd hosts map entry name is for the host short name, the amd mount
|
|
|
29d2b9 |
entry for the short name gets removed. This causes a subsequent mounts
|
|
|
29d2b9 |
for host exports to fail.
|
|
|
29d2b9 |
|
|
|
29d2b9 |
What should happen is the short name amd entry not be removed and a
|
|
|
29d2b9 |
mounted mount entry for the symlinked FQDN mount added so it expires.
