One of the things that anaconda uses kudzu for is determining the list of modules to load. This patch fixes that, along with doing a variety of other things, determined by the following logic: - We want to move to a model where we just load modules from the normal information and aliases exported in sysfs - This means that we are loading (generally) by modalias, not by module name - Ergo, we need to either duplicate all the alias handling, sysfs walking, etc. in anaconda... - Or, we use the system modprobe and udev coldplug. (That is what this implements.) - To use the system modprobe, we either need to hack it to understand the cpio module ball... - Or, we move to just shipping a normal tree of modules. (That is what this implements.) - To do so, either we need a special static version of modprobe... - Or, we switch to a dynamic stage 1 (That is what this implements.) The way module loading now works: - Under normal circumstances, modules are loaded via standard udev coldplug mechanisms - Early module loading is still supported - Passing module options on the commandline is still supported - blacklist=<foo> is now supported, to blacklist automatic loading of a particular module - nofirewire, nousb, etc. are ignored. The only noXX handled is 'noprobe', which disables udev coldplug entirely. - Manual driver selection is still allowed, if necessary. Things not yet modified/fixed in this patchset: - Manual driver selection is aborting in newt somewhere. May be unrelated. - Driver disks are not modified to the new tree layout. Basically, they should now be extracted and copied to /lib/modules/$(whatever)/updates/. Some tweaks with depmod may be necessary to get the aliases in the right place. Size concerns: Before: 7.2MB After: 8.6MB Could be reduced by weaning the glib2 dependencies, not linking zlib statically in modutils, and a couple of other things.
