As Respin is a fork (and is pretty similar to) of RemasterSys, it would make sense to have a synonym for the two, especially because the official site calls it a fork of the more widely-applicable RemasterSys.
I'd be slightly against this because respin isn't just the name for a bit of software, is its own word that has been used around Linux for a long time to mean a re-imagining or at least a re-imaging of a distribution.
And in that sense, it's super-east to see see why they've called it this... But I know I've used it in the generic sense before. Merging a generic into a branded tag feels... Wrong.
Not with me? What if somebody forked Bash and called it Command-Line? We wouldn't even entertain a merge there. I know it's less extreme here but this isn't a hugely used tag... Do we need to do anything?
