here is the next update which brings this multipath to the state i'm not ashamed of it being in udev :) * drop a libdevmapper copy in extras/multipath; maybe discussions w/ Sistina folks will bring a better solution in the future. * drop a putchar usage in libdevmapper to compile cleanly with klibc * drop another such usage of my own in main.c * massage the Makefile to compile libdevmapper against klibc * use "ld" to produce the binary rather than "gcc -static" * stop being stupid w/ uneeded major, minor & dev in main.c:dm_mk_node() * reverse to creating striped target for now because the multipath target is more hairy than expected initialy * push the version code to 009 to be in synch w/ udev builds & run here. binary size is 43ko, which is fairly gratifying after all the efforts I've put to compiling it with klibc :)
