It's indeed pretty clear the naming is inconsistent.

We can't rename the variable in current releases, but we can have new aliases and could deprecate the existing names for the next major release.

And while here, indeed the service name is currently 'tmp' but its only purpose is to provide a memory disk for '/tmp', so 'tmpmfs' could look like a better name.  'var' is similar, but it also populates '/var', so no straight renaming possible here (and a split of functionality does not seem worth the trouble).

Forgetting about renaming, we can still keep the property that the variable starts with the service name and an underscore, and augment it for sub-functionality as appropriate, e.g., use the prefixes 'tmp_' and/or 'tmp_mfs_', 'var_' and 'var_mfs_', etc.

So there are at least several possible ways to have more rational and palatable names then what we have today.
