mount attaches a
High Sierra file system (hsfs) to the file system hierarchy at the mount_point,
which is the pathname of a directory. If mount_point has any contents prior
to the mount operation, these are hidden until the file system 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 extensions, by default they will
be used, enabling support of features not normally available under High
Sierra file systems such as symbolic links, and special files.
- 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 following options are
available:
- 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; interpret 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’.

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.
