All it is is a set of macros to get at the GNU "linker set" abstraction without forcing the user to code in assembly language. Since linker sets were introduced for C++ constructors for virtual base classes, and similar things, it's likely that they are described in the G++/GLD documentation. I don't remember who integrated the SYSINIT stuff; I'm the one who originally wrote it. Probably the integrator would be the person to do the job (I originally wrote the LKM stuff, too, and it's mutated out of all proportion). One of the problems with it is that my initial presentation was alpha level code, but it was quickly integrated anyway. There were a lot of things in it that I would not have done in "real" code (it was more a proof of concept thing). Because it was integrated instead of commented on, I never had a chance to rev. the stuff, so whoever did the integration did a rev. (that I probably should have been tasked with) in the process.
