NAME
rmmount.conf - removable media mounter configuration file
SYNOPSIS
/etc/rmmount.conf
DESCRIPTION
The rmmount.conf file contains the rmmount(1M) configuration
information. This file describes where to find shared
objects that perform actions on file systems after identify-
ing and mounting them. The rmmount.conf file is also used to
share file systems on removable media. It can also direct
the rmmount utility to run fsck on one or more file systems
before mounting them, with the fsck command line options
specified in rmmount.conf.
Actions are executed in the order in which they appear in
the configuration file. The action function can return
either 1 or 0. If it returns 0, no further actions will be
executed. This allows the function to control which applica-
tions are executed. For example, action_filemgr always
returns 0 if the File Manager is running, thereby preventing
subsequent actions from being executed.
To execute an action after a medium has been inserted and
while the File Manager is not running, list the action after
action_filemgr in the rmmount.conf file. To execute an
action before the File Manager becomes aware of the medium,
list the action before action_filemgr in the rmmount.conf
file.
The syntax for the rmmount.conf file is as follows:
# File system identification
ident filesystem_type shared_object media_type [media_type ...]
# Actions
action media_type shared_object args_to_so
# File system sharing
share media_or_file_system share_command_options
# Mount command options
mount media_or_file_system [file_system_spec] -o mount_command_options
# Optionally fsck command options
fsck media_type filesystem_type -o fsck_command_options
Explanations of the syntax for the File system identifica-
tion fields are as follows:

File Formats rmmount.conf(4)
filesystem_type An ASCII string used as the file
system type flag of the mount com-
mand (see the -F option of
mount(1M)). It is also used to match
names passed to rmmount(1M) from
Volume Management.
shared_object Programs that identify file systems
and perform actions. This
shared_object is found at
/usr/lib/fs/filesystem_type/shared_object.
media_type The type of medium where this file
system resides. Legal values are
cdrom, floppy, jaz, rmdisk, and zip.
Explanations of the syntax for the Actions fields are as
follows.
media_type Type of medium. This argument is passed in
from Volume Management as VOLUME_TYPE.
shared_object Programs that identify file systems and per-
form actions. If shared_object starts with
`/' (slash), the full path name is used;
otherwise, /usr/lib/rmmount is prepended to
the name.
args_to_so Arguments passed to the shared_object. These
arguments are passed in as an argc and
argv[].
The definition of the interface to Actions is located in
/usr/include/rmmount.h.
Explanations of the syntax for the File system sharing
fields are as follows.
media_or_file_system Either the type of medium or the
specific file system to share.

share_command_options Options of the share command. See
share(1M) for more information about
these options.
Explanations of the syntax for the Mount command options
fields are as follows:
media_or_file_system Either the type of medium or the
specific file system to share.
file_system_spec Specifies one or more file systems
to which this line applies. Defaults
to "all" file system types.
mount_command_options One or more options to be passed to
the mount command. Multiple options
require a space delimiter.
Explanations of the syntax for the fsck command options
fields are as follows:
media_type The type of removable medium. A
Bourne shell regular expression that
matches names of file system media
whose aliases are listed under
/vol/dev/aliases. Examples include
cdrom0, cdrom1, cdrom*, jaz0, jaz1,
and jaz*.
filesystem_type The type of file system, for exam-
ple, ufs or hsfs, that resides on
the medium specified in media_type.
fsck_command_options One or more options to be passed to
fsck(1M). Multiple options must be
separated by spaces.

File Formats rmmount.conf(4)
The algorithm for the fsck configuration line is as follows:
1. The fsck configuration line tells rmmount to run fsck on
filesystem_type, as described above. The filesystem_type
must be correct for the media_type specified.
2. If filesystem_type is not present, rmmount runs fsck on
all file systems on all media that match media_type.
3. If rmmount.conf contains no fsck configuration line or
contains an fsck configuration line with a media_type
that does not match a medium's alias, rmmount does not
run fsck on the removable medium's file system, unless
mount reports that the file system's dirty bit is set.
Default Values
The following is an example of an rmmount.conf file:
#
# Removable Media Mounter configuration file.
#
# File system identification
ident hsfs ident_hsfs.so cdrom
ident ufs ident_ufs.so cdrom floppy rmdisk pcmem
ident pcfs ident_pcfs.so floppy rmdisk pcmem
ident udfs ident_udfs.so cdrom floppy
# Actions
action cdrom action_filemgr.so
action floppy action_filemgr.so
action rmdisk action_filemgr.so
EXAMPLES
Example 1: Sharing of Various File Systems
The following examples show how various file systems are
shared using the share syntax for the rmmount.conf file.
These lines are added after the Actions entries.
share cdrom*
Shares all CD-ROMs via NFS and applies no access res-
trictions.
share solaris_2.x*
SunOS 5.10 Last change: 18 Feb 2003 4
File Formats rmmount.conf(4)
Shares CD-ROMs named solaris_2.x* with no access res-
trictions.
share cdrom* -o ro=engineering
Shares all CD-ROMs via NFS but exports only to the
"engineering" netgroup.
share solaris_2.x* -d distribution CD
Shares CD-ROMs named solaris_2.x* with no access res-
trictions and with the description that it is a distri-
bution CD-ROM.
share floppy0
Shares the file system of any floppy inserted into
floppy drive 0.
share jaz0
Shares the file system on Jaz drive 0.
Example 2: Customizing mount Operations
The following examples show how different mount options
could be used to customize how rmmount mounts various media:
mount cdrom* hsfs -o nrr
Mounts all High Sierra CD-ROMs with the nrr (no Rock
Ridge extensions) option (see mount_hsfs(1M)).
mount floppy1 -o ro
Will always mount the second floppy disk read-only (for
all file system types).
SunOS 5.10 Last change: 18 Feb 2003 5
File Formats rmmount.conf(4)
mount floppy1 -o ro foldcase
Will always mount the second floppy disk read-only (for
all file system types) and pass the foldcase mount
option.
mount jaz1 -o ro
Mounts the medium in Jaz drive 1 read-only, for all file
system types.
Example 3: Telling rmmount to Check File Systems Before
Mounting Them
The following examples show how to tell rmmount to check
file systems with fsck before mounting them, and how to
specify the command line options to be used with fsck:
fsck floppy* ufs -o f
Performs a full file system check on any UFS floppies,
ignoring the clean flag, before mounting them.
fsck floppy* ufs -o p
Uses the fsck p (preen) flag for all UFS floppies.
fsck cdrom* -o f
Tells rmmount to run fsck before mounting any file sys-
tem on CD-ROM.
fsck jaz* ufs -o f
Tells rmmount to perform a full file system check on any
UFS Jaz media, ignoring the clean flag, before mounting
them.

NOTES
When using the mount options line, verify that the specified
options will work with the specified file system types. The
mount command will fail if an incorrect mount option/file
system combination is specified. Multiple mount options
require a space delimiter.
