- pacman -U http:/xxx fails after 10 seconds, with too low download rate?
  works if called manyally, even in chroot?
   error: failed retrieving file 'cfengine-3.4.4-2-x86_64.pkg.tar.xz' from 10.0.2.2:8080 : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds warning: failed to download
