-Subject: [PATCH] fix(daemon): ensure the /var/lib/docker dir exists
-
-The btrfs driver attempts to stat the /var/lib/docker directory to
-ensure it exists. If it doesn't exist then it bails with an unhelpful
-log line:
-
-```
-2014/05/10 00:51:30 no such file or directory
-```
-
-In 0.10 the directory was created but quickly digging through the logs I
-can't tell what sort of re-ordering of code caused this regression.

-Subject: [PATCH] fix(api): serve until the "acceptconnections" job
-
-This fixes a bug that I encountered when using socket activation with
-docker 0.8.1. When running the first `docker run` it would return:
-"create: command not found".
-
-The root cause was the socket activation code path was starting to
-listen before the "initserver" job had finished. This meant that the
-"create" handler hand't been registered yet leading to the command not
-found error.
-
-In log format it looks like this:
-
-```
-[/var/lib/docker|9d2e78e9] +job initserver()
-2014/03/01 04:05:35 Listening for HTTP on fd ()
-[/var/lib/docker|0d71c177] +job create()
-create: command not found
-[/var/lib/docker|0d71c177] -job create()
-[/var/lib/docker|0d71c177] +job acceptconnections()
-[/var/lib/docker|0d71c177] -job initserver() = OK (0)
-```
-
-To fix the issue select on the activationLock and block until the
-"acceptconnections" job has ran.

-Subject: [PATCH] fix(daemon): prepend host /etc/hosts instead of bind mounting
-
-systemd systems do not require a /etc/hosts file exists since an nss
-module is shipped that creates localhost implicitly. So, mounting
-/etc/hosts can fail on these sorts of systems, as was reported on CoreOS
-in issue #5812.
-
-Instead of trying to bind mount just copy the hosts entries onto the
-containers private /etc/hosts.
