Subject: Add warning on install and configure and --yes option
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=e2239412ee5f64b93633480ac6bf7ea78ef6af54;p=raisin.git

Add warning on install and configure and --yes option

Add a warning when the user requests to install and configure the system
as it is potentially harmful.
Also add a -y option to skip the warning and silently continue anyway.
