I need to install a program into a UML Kernel, this program needs Kernel Sources (Sebek 3) but I don't know how compile this sources. In the Host I used ARCH=um  but if I do the same into guest, get a errors when  do make for the sebek program because doesn't find some .h. For this reason I compile (into guest) without ARCH=um and make sebek it's ok. But I get a error when use insmod (error with the format module), I think for the difference between vermagic values. Someone has some idea
