i just installed kde using binary packages and i was a little worried because the install instructions said to make sure that i set an environment variable called KDEDIR. well, i know how to set variables with export, but they go away when i restart. i looked into ways to set environment variables permenantly, like at startup, etc. only to find that the packages i installed made it so that KDEDIR is set at startup. what i'm trying to figure out now is how it does it. can anybody tell me where this environment variable comes from every time?
