# This script (mostly) only exists because you cannot nest yinst
# commands with yinst (This is a Yahoo-ism that is otherwise
# irrelevant).

The plutonManager at $foundit has been notified to reload its configuration.

Do not expect configuration changes to be instantaneous as the
plutonManager patiently waits for active services to finish. In the
worst case, the plutonManager can wait for over twelve seconds before
uncremoniously evicting a recalcitrant service.
