I'm sure there are 5 people for whom it's easily readable.  For others,
it would be helpful if the description would explain what the default
is supposed to match and if it would have same useful examples.

I am always am what I am.

See, that's one problem, and there are others, like keeping things
changed the way you changed them.  Who says that when you make /tmp
persistent, that the change will persist over the next software or
distribution update or upgrade?  When you start changing things like
that, there are likely to be more and more things over time and it
will be difficult or impossible to maintain that.

So don't say "you can change it".  You can't, really.

Hm, quite a bit, yes.
