samba-vfs-modules 2:4.12.5+dfsg-3ubuntu3 (amd64 binary) in ubuntu groovy

 Samba is an implementation of the SMB/CIFS protocol for Unix systems,
 providing support for cross-platform file sharing with Microsoft Windows, OS X,
 and other Unix systems. Samba can also function as a domain controller
 or member server in both NT4-style and Active Directory domains.
 .
 Virtual FileSystem modules are stacked shared libraries extending the
 functionality of Samba. Some examples are:
  * vfs_acl_xattr: Save NTFS-ACLs in Extended Attributes
  * vfs_audit: record selected Samba VFS operations in the system log
  * vfs_readonly: Make a Samba share read only for a specified time period
  * vfs_recycle: Give the same effect as the Recycle Bin on Windows computers
  * vfs_shadow_copy2: Expose snapshots to Windows clients as shadow copies
  * vfs_worm: Disallow writes for older file
 .
 Note: The runtime dependencies of vfs_ceph and vfs_snapper are moved to
 Recommends.
