Fix swift restart error

Dean Troyer · Dean Troyer · commit b1f6c1835b52 · 2012-03-16T10:49:17.000-05:00
'swift-init all {restart|stop}' exits with '1' if there are any problems
sutting down any swift server, including if they were not running to begin with.
An attempt to address this has already been ignored by the Swift team, and it
would not have completely eliminated the problem, so we'll just be defensive here.
