* Enable IPv6 forwarding if docker daemon provided a default route
* For now this requires the --privileged flag, but this could be hacked
around using `ip netns` madness.
* Empty CRLs don't work.
* Avoids confusing easyrsa during the init step where it thinks an
existing PKI configuration exists.
* Add to ovpn_run to help users that are upgrading and ran genconfig
which now depends on the file being present.
* Use a hardlink to tip toe around permissions issues.
* Convert to an array to simplify the code.
* This breaks running `ovpn_genconfig` multiple times with the same
route argument as the array will just grow. This needs to be fixed in
the future.
* Recommended way to work around this is to remove ovpn_env.sh.
