As I write this, there are two system test builds that have been stuck for many hours, endlessly printing "shepherd[1]: waiting for udevd...":
https://hydra.gnu.org/build/3153725 https://hydra.gnu.org/build/3154365 They are both on i686-linux, and on the 'core-updates' branch, but with two different build slaves (hydra.gnunet.org and guix.sjd.se). I will now abort these builds, to free up build slots for other jobs. Mark
