Subject: Gracefully handle an unsupported distro.
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=90976de1e706f6a068d8ce5fecc6174fe9363d32;p=raisin.git

Gracefully handle an unsupported distro.

When your distro is not supported, handle the case gracefully and let
the user know instead of spitting out bash errors.
