I cannot conceive of any way a function or alias would be defined with
these names unless an ebuild author did it intentionally or a user did
it via /etc/portage/bashrc. In either case, I see no need to prevent
that.

We only want to process tmpfiles for the currently running system.

If ROOT is not /, it indicates we are installing the package for use
on a different system or in a container. In either case, the tmpfiles
would be processed upon boot when that system/container is started.

I find this fairly obvious, but if William wants to document it that's fine.

I disagree; indenting the entire eclass is silly and does not really
improve readability. Also, this is a very common pattern found in
other eclasses.

Sorry, I have no idea what you're trying to say here. Recursive blocks?

This really feels like you're making a personal style suggestion here,
and I personally see nothing wrong with it as-is.
