Additional note:
This does not affect docker when using the overlayfs storage driver. I
am using the vfs storage driver because I am using ZFS which is not
supported by overlayfs.
If one is using ext4 (or another overlayfs supported filesystem) then
this can also be fixed by doing the following:
A workaround may be used to temporarily fix the problem (following on
from the replication instructions above):
[LXD container]
## Install gdb
# apt install gdb -y
## Find docker pid
# cat /run/docker.pid
2624
## Attach gdb and set umask to 022
# gdb --pid 2624
... (attach process)
(gdb) call/o
Please ignore these two lines, just running "docker run" is required:
-# docker create ubuntu

[Host machine]
## Install latest backports lxd
$ sudo apt install lxd/xenial-backports lxd-client/xenial-backports
...
## Initialise lxd default storage pool
$ sudo lxd init
Do you want to configure a new storage pool (yes/no) [default=yes]? yes
