rmmount(1M)
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. The Volume
Management daemon, vold(1M), manages removable media.
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 loca-
tions 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 System Administration Guide: Basic
Administration for more information on the location of CD-
ROM, floppy, and other media without file systems. Also see
volfs(7FS).
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 notifi-
cation to other programs that new media are available. These
actions are shared objects and are described in the confi-
guration file, /etc/rmmount.conf. See rmmount.conf(4).
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.
In order to execute an action, rmmount performs a
dlopen(3DL) on the shared object and calls the action func-
tion defined within it. The definition 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 character 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.
