AFAIK it is the same type of idea but implemented in a different way: the linux kernel
uses several (self-defined) sections, see http://lxr.free-electrons.com/source/include/linux/init.h lines 170ff.
(and 187ff.)

#define __define_initcall(level,fn,id) \
         static initcall_t __initcall_##fn##id __used \
         __attribute__((__section__(".initcall" level ".init"))) = fn

to define the init functions and the order they should be called in.

Cheers,
Jörg.
