From 4bcc947301bedc5ebf430cfaf6e4597bfb174aa7 Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Tue, 16 May 2017 13:43:55 -0400 Subject: Improve detection of snappy to include os-release and kernel cmdline. Recent core snap images (edge channel revision 1886) do not contain the previously known files used to detect that a system is ubuntu core. The changes here are to look in 2 additional locations to determine if a system is snappy.
