From 9f9240d175acee274c04242fd5781094b3f5491b Mon Sep 17 00:00:00 2001 From: Awais Belal Date: Mon, 1 Aug 2016 16:31:43 +0500 Subject: 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.
