Why do we need a grub-error tag?
It will not fit both grub and grub2 at the same time and its a useless tag to follow.
Normally if someone is good at solving grub and grub2 issues he will also know how to solve errors on those tags.
We don't have a unity-error tag, we have unity, we dont have wireless-error, we have wireless.
Why grub-error? Should we kill it?
Yup. You might as well merge grub into grub2 at the same time. If people need to specify Grub v1, they can do that.
Things to consider when discussing this:
grub-error is generally a more serious error - however, while that needs to be taken into consideration, its not really a stopping problem.
Currently, for the moment I have it as a synonym of grub. However, because I didn't merge the tags, we can easily change that to whatever we want, if we need to.
