NAME

       rmmount - removable media mounter for CD-ROM, floppy, Jaz drive, and others

SYNOPSIS

       /usr/sbin/rmmount [-D]

DESCRIPTION

       The  rmmount  utility is a removable media mounter that is executed by volume management whenever a removable medium, such as a CD-ROM or a
       floppy, is inserted. Removable media is managed by an application or a volume manager. rmmount can also be called by using volrmmount(1).

       Upon insertion of a medium and following invocation of the volcheck(1) command, rmmount determines what type of file system (if any) is	on
       that medium. If a file system is present, rmmount mounts the file system in one of the locations listed below.

       For a diskette (floppy):

       /floppy/floppy0		 symbolic link to mounted floppy in local floppy drive

       /floppy/floppy_name	 mounted named floppy

       /floppy/unnamed_floppy	 mounted unnamed floppy

       For a CD-ROM or a DVD-ROM:

       /cdrom/cdrom0

	   symbolic link to mounted CD-ROM in local CD-ROM drive

       /cdrom/CD-ROM_name

	   mounted named CD-ROM

       /cdrom/CD-ROM_name/partition

	   mounted named CD-ROM with partitioned file system

       /cdrom/unnamed_cdrom

	   mounted unnamed CD-ROM

       For a Zip drive:

       /rmdisk/zip0		     symbolic link to mounted Zip medium in local Zip drive

       /rmdisk/Zip_name 	     mounted named Zip medium

       /rmdisk/Zip_name/partition    mounted named Zip medium with partitioned file system

       /rmdisk/unnamed_zip	     mounted unnamed Zip medium

       For a Jaz drive:

       /rmdisk/jaz0		     symbolic link to mounted Jaz medium in local Jaz drive

       /rmdisk/Jaz_name 	     mounted named Jaz medium

       /rmdisk/Jaz_name/partition    mounted named Jaz medium with partitioned file system

       /rmdisk/unnamed_Jaz	     mounted unnamed Jaz medium

       For a generic "rmdisk" drive:

       /rmdisk/rmdisk0

	   symbolic link to mounted removable medium in local removable medium drive

       /rmdisk/rmdisk_name

	   mounted named removable medium

       /rmdisk/rmdisk_name/partition

	   mounted named removable medium with partitioned file system

       /rmdisk/unnamed_rmdisk

	   mounted unnamed removable medium

       If the media is read-only (for example, a CD-ROM or a floppy with write-protect tab set), the file system is mounted read-only.

       If  a file system is not identified, rmmount does not mount a file system. See the  for more information on the location of CD-ROM, floppy,
       and other media without file systems.

       If a file system type has been determined, it is then checked to see that it is "clean." If the	file  system  is  "dirty,"  fsck  -p  (see
       fsck(1M)) is run in an attempt to clean it. If fsck fails, the file system is mounted read-only.

       After  the mount is complete, "actions" associated with the media type are executed. These actions allow for the notification to other pro-
       grams that new media are available.

       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.

       In order to execute an action, rmmount performs a dlopen(3C) on the shared object and calls the action function defined within it. The def-
       inition of the interface to actions can be found in /usr/include/rmmount.h.

       File systems mounted by rmmount are always mounted with the nosuid flag set, thereby disabling setuid programs and access to block or char-
       acter  devices  in  that  file  system. Upon ejection, rmmount unmounts mounted file systems and executes actions associated with the media
       type. If a file system is "busy" (that is, it contains the current working directory of a live process), the ejection will fail.

OPTIONS

       -D    Turn on the debugging output from the rmmount dprintf calls.

FILES

       /usr/lib/rmmount/*.so.1	  shared objects used by rmmount.
