Subject: Allow more-gentle "boot" (instead of "switch") updates
X-Git-Url: http://git.scottworley.com/auto-upgrade-with-pinch/commitdiff_plain/4fa1f9a93369f086f2d8c1635f5550932f056ccc?ds=inline;hp=752d37291d831f952f4998e75b4180a4690fc979

Allow more-gentle "boot" (instead of "switch") updates

Since 26.05, "switch" updates have become more violent, abruptly logging
