I believe config and configure should be merged into configuration.
I would say that all those tags are all meta tags (configuration of what?) and are not actually useful. That said, there are over a thousand questions tagged with it and even 19 followers (really?), so maybe they're here to stay...
We can always ask community/devs to delete tags attached to large numbers of questions.– user9517Jul 23, 2012 at 6:42
I would tend to agree that these are bad tags: If any of them were the only tag on a question it would have zero meaning. As such they should probably be fired, out of a cannon, into the sun. (Disclaimer: I've only glanced at the list of questions half-seriously, vomited in my bucket, and decided the tags were at fault. It could just as easily be the Debugging Tequila's fault...)– voretaq7Jul 23, 2012 at 15:12
configuration are the same, but
configure could also tag a question related to the
./configure step of C/C++ programs and has nothing to do with configuration.
