+Miscellaneous Notes
+-------------------
+
+lib/entropy.c assumes that it can obtain high-quality random number
+seeds at startup by reading from /dev/urandom.  You will need to
+modify it if this is not true on your platform.
+
+vswitchd/system-stats.c only knows how to obtain some statistics on
+Linux.  Optionally you may implement them for your platform as well.
