.SH NAME
rmmount \- removable media mounter for CD-ROM, floppy, Jaz drive, and others
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/rmmount\fR [\fB-D\fR]
.fi

.SH DESCRIPTION
.sp
.LP
The \fBrmmount\fR utility is a removable media mounter that is executed by
volume management whenever a removable medium, such as a \fBCD-ROM\fR or a
floppy, is inserted. Removable media is managed by an application or a volume
manager. \fBrmmount\fR can also be called by using \fBvolrmmount\fR(1).
.sp
.LP
Upon insertion of a medium and following invocation of the \fBvolcheck\fR(1)
command, \fBrmmount\fR determines what type of file system (if any) is on that
medium. If a file system is present, \fBrmmount\fR mounts the file system in
one of the locations listed below.

.sp
.LP
If the media is read-only (for example, a \fBCD-ROM\fR or a floppy with
write-protect tab set), the file system is mounted read-only.
.sp
.LP
If a file system is not identified, \fBrmmount\fR does not mount a file system.
See the \fI\fR for more information on the location of \fBCD-ROM\fR, floppy,
and other media without file systems.
.sp
.LP
If a file system type has been determined, it is then checked to see that it is
"clean." If the file system is "dirty," \fBfsck\fR \fB-p\fR (see
\fBfsck\fR(1M)) is run in an attempt to clean it. If \fBfsck\fR fails, the file
system is mounted read-only.
.sp
.LP
After the mount is complete, "actions" associated with the media type are
executed. These actions allow for the notification to other programs that new
media are available.
.sp
.LP
Actions are executed in the order in which they appear in the configuration
file. The action function can return either \fB1\fR or \fB0\fR. If it returns
\fB0\fR, no further actions will be executed. This allows the function to
control which applications are executed.
.sp
.LP
In order to execute an action, \fBrmmount\fR performs a \fBdlopen\fR(3C) on the
shared object and calls the action function defined within it. The definition
of the interface to actions can be found in \fB/usr/include/rmmount.h\fR.
.sp
.LP
File systems mounted by \fBrmmount\fR are always mounted with the \fBnosuid\fR
flag set, thereby disabling setuid programs and access to block or character
devices in that file system. Upon ejection, \fBrmmount\fR 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.
