# HG changeset patch # User Richard Maciel <rmaciel@linux.vnet.ibm.com> # Date 1243891178 10800 # Node ID dc7ef55a1fe9870280e369096a4ed267e3eaa4ec # Parent 849171d2fbc0adbba613516bbdea4b78199178dd Added support to convert data in the internal format to the format used by the BootDevices property #2: - Code style changes - Added cu_statusf() calls to provide specific error messages to the user #3: - cu_statusf() calls now use the local broker instead of the global one Signed-off-by: Richard Maciel <rmaciel@linux.vnet.ibm.com> diff -r 849171d2fbc0 -r dc7ef55a1fe9 schema/VSSD.mof --- a/schema/VSSD.mof Mon Jun 01 14:01:21 2009 -0700 +++ b/schema/VSSD.mof Mon Jun 01 18:19:38 2009 -0300 @@ -27,7 +27,7 @@ [Description ("The device to boot from when in fully-virtualized mode."
