+Subject: [PATCH] init-install.sh: /etc/mtab make a softlink 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.
