Z-stick serial port issue after deleting tmp & cache

When I delete the cache and tmp directories (say to install a snapshot Zwave .jar) my Aeon zstick loses connectivity to the serial port upon restart. I then go into the console and type (feature:install openhab-transport-serial) and everything works fine. My question is; Is there a file I can modify so the openhab-transport-serial feature is added during the openhab2 restart? Just trying to clean things up a bit.
