init-install*: /etc/mtab make a link rather than a copy
Using a copy would only make management of devices erroneous and makes the system unstable in some scenarios as tools will have to manipulate both files separately. A link ensures that both files /proc/mounts and /etc/mtab will have the same information at all times and this is how it is handled on newer systems where there is such a need. Same is suggested by busybox. Signed-off-by: Awais Belal <awais_belal@mentor.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
