Hi Lennart,
I reformatted my partition and tried again. :-) Importing now works,
if I disabled the
verification.

With the verification enabled, I still get the following error. Is this a
problem of my setup or a systemd-problem?

The trustdb exist:
# ls -al ~/.gnupg/trustdb.gpg
-rw------- 1 root root 40 Feb 18 :56 /root/.gnupg/trustdb.gpg
And changing permissions does not help either. The error still occures.
# ls -al ~/.gnupg/trustdb.gpg
-rw-r--r-- 1 root root 40 Feb 18 :56 /root/.gnupg/trustdb.gpg
Another problem occures, when I try to remove an image.
# machinectl list-images

trusty-server-cloudimg-amd64-root subvolume no 342.1M Thu

It fails with "Access Denied".
# machinectl remove trusty-server-cloudimg-amd64-root
Could not remove image: Access denied
What works is to delete the sub-volumes with `btrfs`:
btrfs subvolume delete /var/lib/machines/middleman-presentation/ -c
I'm new to btrfs. Anything I did wrong?
cat /etc/fstab
UUID=<uuid> /var/lib/machines btrfs
defaults,noatime,autodefrag,compress=lzo,space_cache 0 0
This is the output of mount
mount
/dev/vda2 on /var/lib/machines type btrfs

This is my partition table
# lsblk -f

I fixed this by enabling quotas, but the error message mentioned above still
occures. Maybe the quota stuff should be mentioned in the readme?
# btrfs quota enable /var/lib/machines/
# btrfs qgroup show /var/lib/machines/

With the btrfs-filesystem download docker images now works fine:

Running them looks good! Maybe you want to add a warning, that CMD and
ENTRYPOINT from Dockerfile are ignored. At least it looks like that.
Thanks a lot,
Cheers
