What this commit has added is the ability for the administrator to change this behaviour on a global basis via a sysctl. (rather than stabbing at it w/ddb) Really, the fixup/whine/bus-error choice should be made on a per-process basis (as in Digital UNIX's uac command). This allows you to turn on silent fixups for broken closed-source programs you cannot fix.. ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
