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 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. 

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 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. 

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”. 

FILES

/etc/mnttab table of mounted file systems

/etc/vfstab list of default parameters for each file system

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.
