MTAB(5)
NAME
mtab − mounted file system table
USAGE
#include <fstab.h> #include <mtab.h>
DESCRIPTION
On DOMAIN/IX systems, the mtab file, /etc/mtab, is a link to the per-node file `node_data/etc.mtab. It is created upon installation of DOMAIN/IX software. The file contains a table of devices mounted by the mount(8) command. Mount adds entries to this file; umount(8) removes them.
The table is a series of mtab structures, as defined in <mtab.h>. Each entry contains the null-padded name of the place where the special file is mounted, the null-padded name of the special file, and a type field, one of those defined in <fstab.h>. The special file has all its directories stripped away; that is, everything through the last slash (/) is discarded. The type field indicates whether the file system is mounted read-only or read-write.
This table is present for reference purposes only. It does not matter to mount if there are duplicated entries, nor to umount if a name cannot be found.

NOTES
Owners of diskless DOMAIN Nodes can create this file in a `node_data directory on their disked partner by running the mkptnr(8) command.
