Recent illumos has added Linux compatibility functions to support LX 
Zone functionality and these compatibility functions might be picked 
up and used by accident by software which targets Linux.  I don't know 
if there is an emulation of inotify(7) but it seems like something 
important to emulate for LX Zones.

Regardless, the Dtrace Toolkit provides scripts (opensnoop and 
iosnoop) which allows observing all I/O activity on the system and so 
it should quickly reveal the offender.
