This is dmraid failing to link to the newer LVM.
Problem persists with sys-kernel/genkernel-3.5.2.3 for me.
Any update on this one?
I too am running into this. Interestingly the version of LVM that genkernel is trying to use, at least at the time of my last sync, is masked - so my actual userland divorced from the ramdisk builds everything just fine. Obviously it's missing links to pthread and and libm - though I'm not entirely sure if the "correct thing to do" is in this case to force these to link together. If I'm not mistaken, at one point LVM had stuff patched by statically linked in the genkernel ramdisk for probably a good reason.
When the system dmraid's compiled static against lvm2[-udev] it sets LIBS="-ldevmapper -lm -lrt -lpthread" based on the pkg-config --static output; it makes sense to me that this is what we would need to set when we build dmraid within genkernel as well, right now it's hard-coded to just LIBS="-ldevmapper"

@axs: thanks for that catch. Hopefully commit 10b971c captures that correctly. Can somebody with a dmraid system please test, and then we can close this bug out.
My bad, I should have subscribed to this bug. I am not in town right now but when I get back I can test a new genkernel initrd with this dmraid to see if it builds (and subsequently boots). I should be back before the new year.
