Not for this case. Asterisk uses the AST_RUN_DIR (/var/run/asterisk or
whatever) for:

* asterisk.pid
* alt.asterisk.canary.tweet.tweet.tweet
* asterisk.ctl

alt.asterisk.canary.tweet.tweet.tweet is intended for communicating with
a subprocess of asterisk, and thus can reside in aprivate directory. The
pid file (if anyone else relies on it) and asterisk.ctl (the socket used
by asterisk -rx) are "published". asterisk -r is a different instance of
asterisk.

It's still a surprise for me, as generating a private run directory
seems like a relatively common case.
