rmmount(1M) System Administration Commands rmmount(1M)NAMErmmount - 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 sys‐
tem 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 sys‐
tem. 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 notification to other pro‐
grams that new media are available. These actions are shared objects
and are described in the configuration file, /etc/rmmount.conf. See
rmmount.conf(4).
Actions are executed in the order in which they appear in the configu‐
ration file. The action function can return either 1 or 0. If it
returns 0, no further actions will be executed. This allows the func‐
tion 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 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 direc‐
tory of a live process), the ejection will fail.
OPTIONS-D Turn on the debugging output from the rmmount dprintf calls.
