NAME
pfs_fstab, mtab — static file system mounting table, mounted file systems table
DESCRIPTION
The
/etc/pfs_fstab
file contains entries for CD-ROM file systems and disc images to mount
using the
pfs_mount(1M)
command, which is normally invoked by
rc(1M)
script at boot time. This file is used by various utilities such as
pfs_mount,
and
pfs_umount.
The
/etc/mtab
file contains entries for file systems
currently
mounted, and is read by programs using the routines described in
getmntent(3X).
umount
(see
mount(1M))
removes entries from this file.
Each entry consists of a line of the form:
filesystem directory type options freq pass
- filesystem
is the pathname of a raw or block-special device, the name of a remote
file system in
host:pathname
form, or the name of a file created with MakeDisc.
- directory
is the pathname of the directory on which to mount the file system.
- type
is the file system type, which can be one of:
- pfs-iso9660
to mount a device as iso9660.
- pfs-hsfs
to mount a device as hsfs.
- pfs-rrip
to mount a device as rrip.
- pfs-nfs
to mount an exported
PFS
file system
- options
contains a comma-separated list (no spaces) of mounting options,
some of which can be applied to all types of file systems, and
others which only apply to specific types.
options
valid on
all
file systems:
- ro
Even if not specified, this option is implied.
- suid|nosuid
Setuid execution allowed or disallowed.
- bg|fg
If the first attempt fails, retry in the background, or,
in the foreground.
- retry=n
The number of times to retry the mount operation.
- rsize=n
Set the read buffer size to
n
bytes.
- timeo=n
Set the
PFS
timeout to
n
tenths of a second.
- retrans=n
The number of
PFS
retransmissions.
- soft|hard
Return an error if the server does not respond, or continue the
retry request until the server responds.
- intr
Allow keyboard interrupts on hard mounts.
options
specific to
iso9660
and
hsfs
file systems:
- xlat=xlat_flags
xlat_flags
is a colon (:) separated list of translation options. Currently supported
are no_version, dot_version, lower_case, and unix.
- freq
is the interval (in days) between dumps.
For a PFS file system, this should be 0.
- pass
is the
fsck(1M)
pass in which to check the partition.
For a PFS file system, this should be 0.
A pound-sign
(#)
as the first character indicates a comment line which
is ignored by routines that read this file.
The order of records in
/etc/pfs_fstab
is important because
fsck,
mount,
and
umount
process the file sequentially; an entry for a file system must appear
after
the entry for any file system it is to be mounted
on
top of.
EXAMPLES
/dev/sr0 /cd-rom pfs-iso9660 ro,suid 0 0
example:/home/user /home/user pfs-nfs ro,hard,fg 0 0
