From 47531b5050e82f361a35c670f14f542cdce25d74 Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Fri, 6 Jan 2012 15:19:41 -0500 Subject: init: mount separate /usr Use findmnt to detect the existance of a separate /usr partition existing in the real root. If it does exist, fetch the options for it and mount it. This currently makes a lot of assumptions and won't be very friendly towards something such as a dm-crypt device.
