mount_hsfs(1M)
NAME
mount_hsfs - mount hsfs file systems
SYNOPSIS
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
DESCRIPTION
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.
OPTIONS
generic_options
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
required.
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.
notraildot
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.
nomaplcase
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.
nosuid
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.

NOTES
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.
