Generated arguments will be added only if matching arguments were not
specified by the user. User arguments will be placed after generated
arguments. This allows the user to override any generated configuration
values.
* Systemd service currently marks the mount as read-only, and this is
regarded as good practice for server/daemon only operation.
* Don't create /etc/openvpn/ccd as the mount may be read-only.
* Append the client-config-dir command line argument if it is found to
avoid mkdir operation.
* Mount can easily be modified using a different docker run line with
":ro" on the volume mount.
* 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.
