svn commit: r898787 - /incubator/vcl/trunk/managementnode/lib/VCL/Module/OS/Windows/Version_5.pm

Author: arkurth
Date: Wed Jan 13 14:52:07 2010
New Revision: 898787

URL: http://svn.apache.org/viewvc?rev=898787&view=rev
Log:
VCL-145
Created the following new subroutines in Version_5.pm to support the dynamic creation of the sysprep.inf file for Windows XP and Windows Server 2003:
run_sysprep()
get_sysprep_inf_contents()
get_sysprep_inf_mass_storage_section()
get_driver_inf_paths()
set_device_path_key()

These subroutines utilize the winProductKey table to dynamically inject the correct product key (affiliation-specific or global) into the sysprep.inf file. They also scan the driver files to construct the SysprepMassStorage section of sysprep.inf and to set the DevicePath registry key. As a result, the spdrvscn.exe utility is no longer needed and the template sysprep.inf file does not need to be stored on the management node or in the repository.

+=head2 get_driver_inf_paths
+
+ Parameters  : Driver class (optional)
+ Returns     : Array containing driver .inf paths
+ Description : This subroutine searches the node configuration drivers directory
+               on the computer for .inf files and returns an array containing
+               the paths of the .inf files. The node configuration drivers
+               directory is: C:\cygwin\home\root\VCL\Drivers
+               
+               An optional driver class argument can be supplied which will
+               cause this subroutine to only return drivers matching the class
+               specified. Each driver .inf file should have a Class= line which
+               specified the type of device the driver is intended for. This
+               argument can be a regular expression. For example, to search for
+               all storage drivers, pass the following string to this
+               subroutine:
+               (scsiadapter|hdc)
+               
+               The driver paths are formatted with forward slashes.
