I'm a fan of the new KLD system, so removing LKM build support is IMHO the right thing to do. I've been working on an embedded system which boots from a 2Mb flash chip without a filesystem. Before KLDs came along, I couldn't use LKMs for I/O devices because of the overhead of having to ship GNU tools too. Now all custom code lives in KLDs which get loaded by the application which replaces init and a simple 20 line kernel config file suits all target hardware versions. -- John Birrell - jb@cimlogic.com.au; jb@freebsd.org http://www.cimlogic.com.au/ CIMlogic Pty Ltd, GPO Box 117A, Melbourne Vic 3001, Australia +61 418 353 137 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
