0001-write-pid-file-immediately-after-daemonizing.patch (upstream)
* Fixes writing PID file when starting tunnels with --management-hold.

openvpn-no-build-date.patch (kristov/roland)
* Prevents the build date/time from being compiled in.

openvpn-sigusr1-restart.patch (kristov)
* Never map SIGUSR1 to SIGHUP. SIGUSR1 does cleanups as destroying the
  environment. When a subsequent SIGUSR1 is mapped to SIGHUP, do_close_tun()
  is called which accesses the previously freed environment, causing an
  assertion failure.

openvpn-writeport.patch (babel/roland)
* Writes the port used for management console to a file.
