I ran into the same problem building systemd master last week. The issue is that libudev.so now has a reference to $out/lib/udev/hwdb.bin. So it's not an RPATH issue. Probably we just need to patch out the use of $out/lib/udev/hwdb.bin, since we don't have that file anyway (we use /etc/udev/hwdb.bin). You can find the exact cause of these cycles using good old "grep -r". -- Eelco Dolstra | LogicBlox, Inc. | http://nixos.org/~eelco/ _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
