====== Idunn's modules handling ======

//Idunn// messes with modules in three phases (while ''udev'' is running): preloading, //cold-plugging// and //hot-plugging//. 

===== preloading and blacklisting =====

//Idunn// looks at the kernel command line (''/proc/cmdline'') for a ''modules=...'' list. This list is delimited using ':' (colons), and each entry can mean a loading or blacklisting.

A blacklisting entry is of the form "-foo", a minus followed by the name of the module to blacklist.
A loading entry is of the form "foo[,arg1[,arg2[...]]]", the module name followed by the arguments we want to pass to modprobe using a comma as delimiter.

===== cold-plugging =====

After the hardcoded part is finished, //Idunn// uses ''udevtrigger'' to ask ''udev'' to load every module available which is needed by the system. And waits until ''udev'' thinks it's done.

===== hot-plugging =====

After //cold-plugging// udev will be running until we finally ''switchroot'', so in theory you could plug devices and get the modules loaded if you are fast enough.
