Subject: [OE-core] [[PATCH v3] 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.
