We could add aliases at install time. Every time we install a version using an alias, we add that as an alias. E.g. rig add next will add R-next. When we call rig add next again, then we update the alias. (It might refer to a new version now.)
We can also update aliases with rig alias update.
rig alias update can have an option to add "standard" aliases: oldrel, next, release, devel.

OTOH, it is probably not worth adding a new rig alias command for this. rig ls already lists the aliases, and rig system make-links could also update the aliases, unless opt out.

I'll update rig system make-links later.

Actually, I like this as it is. It would be weird to update aliases from system make-links, if no new version is installed.

Instead we could have a rig system update-aliases subcommand, but we could wait with that until we have generic, user-defined aliases.
