Alan wrote a paper on the ON build sometime ago for the SunTech Conference in 2001. See
http://mediacast.sun.com/share/sch/d-exacct-builds-suntech-2001.pdf for details. (A number of aspects have changed since this paper was written; for instance, the task's ancestor is now part of the default task record and PRIV_PROC_TASKID can be assigned to a user, meaning that they can call settaskid(2) without being root.) - Stephen -- Stephen Hahn, PhD Solaris Kernel Development, Sun Microsystems [EMAIL PROTECTED] http://blogs.sun.com/sch/ _______________________________________________ tools-discuss mailing list [email protected]
