You need rev 1.70 or newer of /sys/kern/kern_exec.c. I've manually patched kern_exec.c (rev 1.69 introduced a <pioctl.h> include and a STOPEVENT() call, make depend wasn't so happy with those) and now I'm awaiting... hoping it won't panic anymore :) BTW, I can't find PR#5313 (GNATS didn't find it, or I'm not using the right query params) that "bde" made reference to in r1.70 CVS log; any kind soul care to help me finding it ? > > -DG > > David Greenman > Core-team/Principal Architect, The FreeBSD Project > Thank you very much.
