This is also related to the identcpu.c and i686_mem.c files. While building a very small kernel (nanobsd :) for i486 based system I've noted that i686_mem.c compiled always regardless of 'cpu' keyword in the config file (why one need it on 486...). Similarly, identcpu.c code can reduced by excluding probes and corresponding messages for Pentiums if one needs only i486 support. A more general question: should we allow more options to exclude optional and obsolete parts of the kernel ? For example, I've ripped out aout, aio and jail related code without any effect on functionality for my particular system. -- Boris Popov http://www.butya.kz/~bp/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
