You're asking someone to do work for something that's not really valuable to them. There are certain boot code features that require the use of a.out kernels; this is less an issue than it was, but there were a number of things lost when we went to the new loader that are important for embedded environments. Cross-building for older platforms (not as big an issue, IMO). Other reasons I haven't even thought of yet.... 8-). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
