libpam-mount binary package in Ubuntu Focal s390x

 This module is aimed at environments with central file servers that a
 user wishes to mount on login and unmount on logout, such as
 (semi-)diskless stations where many users can login.
 .
 The module also supports mounting local filesystems of any kind the
 normal mount utility supports, with extra code to make sure certain
 volumes are set up properly because often they need more than just a
 mount call, such as encrypted volumes. This includes SMB/CIFS, FUSE,
 dm-crypt and LUKS.
