I'm setting up a server and want to keep from having to manually enable/disable certain permissions on each start. How would I go about automating this process?

Permissions are persistent as long as your server has saved before shutdown. Simply run the commands, save (or wait for a save), and enjoy. Permissions tutorial for reference: https://umod.org/documentation/plugins/permissions

Thanks @Wulf for the prompt response -- and also for all the work I see from you around here!
