Just for the record: Secure Computing's Sidewinder Firewall
running on a BSD/OS with S.C.'s proprietary extensions
uses a similar mimic to reference files depending on
which "burb" (i.e. zone of trust) a process is running in.

Cool to see it in Dragonfly and hopefully FreeBSD. I can
imagine interesting setups for HA systems, for example:

script -> script${AM_I_ACTIVE_OR_PASSIVE}

Patrick
