The filesystem type is set when the filesystem is created
and cannot be changed.
mounts the filesystem as read-only so that no changes can be made
to the filesystem while it is mounted.
You must mount CD-ROM filesystems and filesystems
on write-protected floppy disks as read-only to prevent errors.
mounts the filesystem with write permissions enabled.
Changes can be made to the filesystem while it is mounted.
When mounting remote filesystems, read/write permissions
might already be limited by the NFS server.
For more information, see
``Setting export access permissions'' in the Networking Guide.
mounts the filesystem immediately;
the filesystem remains mounted until you unmount it
or you reboot the system.
At System Startup
does not mount the filesystem immediately.
The next time you boot the system,
the filesystem is mounted automatically.
Check and Repair Options
changes the filesystem checking mount options.
``Check and repair options''.
These options are not available for CD-ROM filesystems
(High Sierra, ISO9660, Rockridge), NFS-mounted filesystems,
or DOS filesystems;
you cannot check and repair these filesystem types with the
Filesystem Manager or
changes the filesystem-specific advanced options.
Which advanced options are available depends on the type of filesystem
you are modifying
(these options are not available for
XENIX filesystems). See:
