bindfs binary package in Ubuntu Focal s390x

 bindfs is a FUSE filesystem for mirroring a directory to another
 directory, similarly to mount --bind. The permissions of the mirrored
 directory can be altered in various ways.
 .
 Some things bindfs can be used for:
  - Making a directory read-only.
  - Making all executables non-executable.
  - Sharing a directory with a list of users (or groups).
  - Modifying permission bits using rules with chmod-like syntax.
  - Changing the permissions with which files are created.
 .
 Non-root users can use almost all features, but most interesting
 use-cases need user_allow_other to be defined in /etc/fuse.conf.
