When compiling the kernel I can select to : omit 386/486-thingies and optimise the binaries for 686. Can I do the same for : the 'world'-target? Yes. I do this all the time. Except I have an Pentium II 500MHz box. I do a make buildworld there and an installworld on the 486 box. I have to make sure that the /usr/obj and /usr/src trees are the same between the two (mounted in the same place, same sym links, etc) and that my /etc/make.conf is the same. Otherwise it just works. You have to have /usr/obj writable by root, so it can't be read only :-(, but that's about the only snag I can think of. Of course I have no PPro or Pentium II specific optimizations in my tree. They don't seem to help much anyway. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
