Default multipath-tools/multipathd multipathd.init.redhat

CVSROOT: /cvs/dm
Module name: multipath-tools
Branch: RHEL5_FC6
Changes by: bmarzins@sourceware.org 2008-08-28 19:22:33

Modified files:
multipathd : multipathd.init.redhat

Log message:
Fix for bz #456228. Patch applied from bugzilla. The multipath init script now
refuses to stop multipathd when the root device is a multipath device. This
was causing problems with shutdown on iSCSI devices.
