Subject: [PATCH] RH: don't start without a config file
If /etc/multipath.conf doesn't exist, don't start multipathd and blacklist
all devices when running multipath. A completely blank configuration file
is almost never what users want. Also, people may have the multipath
packages installed but don't want to use them. This patch provides a
simple way to disable multipath. Simply removing or renaming
/etc/multipath.conf will keep multipath from doing anything.
