Mindi: improved handling of finding kernel module files

[Matthew Cline]

Attached is a patch that makes two improvements to the handling of finding kernel module files. Less importantly, when a module file can't be found, it notes in the log file whether or not the module is a live one (one the system is actually currently using) or is one from EXTRA_MODS:

module nvidia --> [live module file not found]
module lvm-mod --> [extra module file not found]

This should be useful for trouble-shooting, since a missing live module is probably a lot more likely to cause trouble than a missing extra module.

More importantly, if a module's name uses "_"s but its filename uses "-"s, then mindi will now be able to find the file.

Here's a slightly improved patch: if mindi can't find a kernel module file normally, and can't find it by replacing "_"s with "-s", then it tries "modprobe --dry-run -v ${module}". For example, on my system, the module named nvidia has the filename nvidia-current, which this technique can find.

I recognize that there is indeed a long time issue with the finding of modules in mindi. However, your patch can not be applied as is. For example if you work with the non runnig kernel (which mindi supports) it will not give the right answer, becasue modprobe uses only the running kernel.

For the moment - and _ in module names are handled by duplicating the module name in the list, in order to have both. Not elegant but works.

I applied a portion of your patch for printing more user friendly messages when a module is not found. Thanks for the suggestion. Will be in next mindi. (part of [2471)
