mount_hsfs - mount hsfs file systems


     mount -F hsfs [generic_options] [-o FSType-specific_options]
     [-O ]  special | mount_point

     mount -F hsfs [generic_options] [-o FSType-specific_options]
     [-O] special mount_point


     mount attaches a  High Sierra file  system   (hsfs)  to  the
     file system hierarchy at the mount_point, which is the path-
     name of a directory.  If mount_point has any contents  prior
     to the mount operation, these are hidden until the file sys-
     tem is unmounted.

     If  mount is invoked with  special or   mount_point  as  the
     only  arguments,   mount will search  /etc/vfstab to fill in
     the    missing    arguments,    including    the     FSType-
     specific_options; see mount(1M) for more details.

     If the file system being mounted contains Rock Ridge  exten-
     sions,  by  default  they  will be used, enabling support of
     features not normally available under High Sierra file  sys-
     tems such as symbolic links, and special files.


           See mount(1M) for the list of supported options.

     -o    Specify   hsfs  file  system  specific  options.    If
           invalid  options  are  specified, a warning message is
           printed and the invalid options are ignored. The  fol-
           lowing options are available:

           global |  noglobal
                 If global is specified and supported on the file
                 system,  and the system in question is part of a
                 cluster, the file system will be globally  visi-
                 ble  on all nodes of the cluster. If noglobal is
                 specified, the mount will not be globally  visi-
                 ble. The default behavior is noglobal.

           ro    Mount the file system read-only.  This option is

           nrr   no Rock Ridge:  if  Rock  Ridge  extensions  are
                 present  in the file system, ignore them; inter-
                 pret it as a regular High Sierra file system.

                 File names on High Sierra file  systems  consist
                 of a proper name and an extension separated by a
                 '.' (dot) character.  By default, the separating
                 dot is always considered part of the file's name
                 for all file access operations, even if there is
                 no  extension  present.  Specifying   notraildot
                 makes it optional to specify the trailing dot to
                 access a file whose name lacks an extension.

                 Exceptions: This option  is  effective  only  on
                 file systems for which Rock Ridge extensions are
                 not active, either because they are not  present
                 on  the  CD-ROM,  or they are explicitly ignored
                 via the nrr option. If Rock Ridge extensions are
                 active,  hsfs quietly ignores this option.

                 File names on High Sierra cdroms  with  no  Rock
                 Ridge  extensions  present  should  be uppercase
                 characters only. By  default,   hsfs  maps  file
                 names  read  from  a  non-Rock Ridge disk to all
                 lowercase characters. nomaplcase turns off  this
                 mapping. The exceptions for
                  notraildot discused above apply to  nomaplcase.

                 By default  the  file  system  is  mounted  with
                 setuid   execution  allowed.  Specifying  nosuid
                 causes the file system to be mounted with setuid
                 execution disallowed.

     -O    Overlay mount.  Allow the file system  to  be  mounted
           over  an  existing  mount point, making the underlying
           file system inaccessible.  If a mount is attempted  on
           a  pre-existing mount point without setting this flag,
           the mount will fail, producing the error device busy.

     If the directory on which a file system is to be mounted  is
     a symbolic link, the file system is mounted on the directory
     to which the symbolic link refers, rather than on top of the
     symbolic link itself.
