Missing tag wikis are common - Tags are created when there is a question that needs them, not when we feel like we should make a tag.

As such, usually a tag wiki is not added and by the time someone realizes, it has long been forgotten.

**That said**: [tag:encrypted-partition] is a synonym to [tag:encryption], so there is really no need to add a tag wiki to it. The tag wiki for [tag:encryption] should be sufficient.

[tag:partitions] on the other hand could use a tag wiki. Anyone can suggest an edit to these tag wikis, which then [has to be approved](http://askubuntu.com/help/privileges/approve-tag-wiki-edits). And, as far as I can tell, there already is an edit pending.
