9 mnttab \- mounted file system table
10 .SH DESCRIPTION
11 .sp
12 .LP
13 The file \fB/etc/mnttab\fR is really a file system that provides read-only
14 access to the table of mounted file systems for the current host.
15 \fB/etc/mnttab\fR is read by programs using the routines described in
16 \fBgetmntent\fR(3C). Mounting a file system adds an entry to this table.
17 Unmounting removes an entry from this table. Remounting a file system causes
18 the information in the mounted file system table to be updated to reflect any
19 changes caused by the remount. The list is maintained by the kernel in order of
20 mount time. That is, the first mounted file system is first in the list and the
21 most recently mounted file system is last. When mounted on a mount point the
22 file system appears as a regular file containing the current \fBmnttab\fR
23 information.

229 The \fBmnttab\fR file system provides the previously undocumented
230 \fBdev=\fR\fIxxx\fR option in the option string for each mounted file system.
231 This is provided for legacy applications that might have been using the
232 \fBdev=information\fR option.
233 .sp
234 .LP
235 Using \fBdev=\fR\fIoption\fR in applications is strongly discouraged. The
236 device number string represents a 32-bit quantity and might not contain correct
237 information in 64-bit environments.
238 .sp
239 .LP
240 Applications requiring device number information for mounted file systems
241 should use the \fBgetextmntent\fR(3C) interface, which functions properly in
242 either 32- or 64-bit environments.
