That sounds like ktrace. However, in System V there's another strace:
strace(1M) strace(1M)
NAME
strace - print STREAMS trace messages
SYNOPSIS
strace [ mid sid level ] ...
DESCRIPTION
strace without arguments writes all STREAMS event trace
messages from all drivers and modules to its standard out-
put.
If this is what you're talking about, it can't work, because we don't
do STREAMS.
