This issue is now solved. The root was the fact that I installed Fedora from the minimal raw image this way: # systemd-nspawn -M Fedora-Cloud-Base-22_Beta-20150415.x86_64.raw --bind=/var/lib/machines/poppy:/mnt So in that case, only /var/lib/machines/poppy was populated by the installation. The solution was: # systemd-nspawn -M Fedora-Cloud-Base-22_Beta-20150415.x86_64.raw --bind=/var/lib/machines/poppy:/mnt --bind=/var/lib/machines/poppy/etc:/mnt/etc --bind=/var/lib/machines/poppy/var:/mnt/var -- google.com/+arnaudgabourygabx -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
