The executables invoked by the ZED in response to a given zevent have been generically referred to as "scripts". By convention, these scripts have aimed to be /bin/sh compatible for reasons of portability and comprehensibility. However, the ZED only requires they be executable and (ideally) capable of reading environment variables. As such, these scripts are now referred to as ZEDLETs (ZFS Event Daemon Linkage for Executable Tasks).
