--- Comment #1 from Jilles Tjoelker <jilles at FreeBSD.org> ---
There is nothing that sets $name; each rc.d script must set it itself. To match
documentation (rc.conf(5)) that states that shell variables can be set such as
⟨name⟩_nice, the name itself needs to be a valid shell variable name.

So if an rc.d script sets name to a literal, it must be a valid shell variable
name. If a script can be linked to multiple names for multiple instances of a
service, this translates to a requirement on the administrator about which
names they can use. Sanitization here may as well make things more confusing.
