Thanks for any thoughts. You can use /usr/bin/kenv to set kernel env variables, or you can have your module register a dynamic sysctl variable that the user can tweak after the module has been loaded. I've used the sysctl method myself and it works fine. -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
