zmnt
NAME
zmnt
−
Expands the read/write files onto the RAM disk.
SYNOPSIS
zmnt [-c] <directory>
zmnt [-c] -t <file>
zmnt [-c] –l
DESCRIPTION
zmnt
expands files from flash onto the RAM disk that have been previously saved with
zsync
.
The
init
process runs
zmnt
to expand the files in flash onto RAM file system. The user may
use
zmnt
to expand the files at anytime and may place them in any directory. For example,
zmnt /tmp
will expand the files under the directory
/tmp
.
Booting the kernel with
-i
instructs the
init
process to skip the
zmnt
stage After booting in
this way,
zmnt
can be used for correcting a problem file in the read-write file system.
The
-t
option can be used to save the configuration of a switch to a tar file. A tar file can be
copied to another switch and saved with
zsync -t
. As a result, the configuration of a switch
may be cloned to other switches.
The
-c
option is used to mount the custom overlay. See
zsync
for a description of custom
verses dynamic overlay.
OPTIONS
-c Read saved files from the custom overlay
-t <file>
Save the overlay into the specified <file> in tar format.
<directory> The directory under which the overlay files are
expanded, or the file to which the tar image is saved.
-l List files in selected overlay, do not unpack.
EXAMPLES
In the following example,
zmnt
the current overlay into a tar file called
overlay.tar
