rmmount(1M) System Administration Commands 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 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 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 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
