    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 identifying 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 applications 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 identification fields are as follows:

    filesystem_type An ASCII string used as the file system type flag of the mount command (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 perform 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 example, 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.

    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 restrictions.

    share solaris_2.x*

    Shares CD-ROMs named solaris_2.x* with no access restrictions.

    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 restrictions and with the description that it is a distribution 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).

    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 system 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.
