with Tumbleweed 6.1.8-1 and prior versions a user could mount a NAS connected
via thunderbolt with "sudo mount -t cifs //169.254.8.252/NAS ~/Mount/NAS
--verbose -o user=username"

After distribution upgrade the user can no longer access the NAS and when
attempting to access the mounted folder receives "Error opening directory
'directory name': No such file or or directory.

This is repeatable:  rollback to 6.1.8-1 NAS again becomes accessible to user,
distribution upgrade again and user no longer has access.

Prior to upgrade the owner of the cifs mounted folders is User with Read &
Write Access.  After upgrade, the owner of the cifs mounted folder is root with
Read & Write access.
