 I just checked with FreeBSD 6.2 release.  Without  
 _KPOSIX_PRIORITY_SCHEDULING in the kernel, attempting to run  
 executables from linux-sun-jdk14 causes core dumps:
 
 Apr 12 19:47:14 xev kernel: cmd java pid 88362 tried to use non- 
 present sched_getscheduler
 Apr 12 19:47:14 xev kernel: pid 88362 (java), uid 0: exited on signal  
 6 (core dumped)
 
 sched_getscheduler() is supplied by _KPOSIX_PRIORITY_SCHEDULING,  
 which is enabled in GENERIC.  I guess an end-user could figure out  
 the problem from the error message, but it would be nice if the  
 requirement was documented somewhere (eg. in the pkg-message, as I  
 suggested).
 
 Cheers,
