I think grog and others have raised some interesting points regarding what the defaults should be. IMO, 'make buildkernel' should emulate the following steps from the current process: config KERNELNAME cd ../../compile/KERNELNAME make depend make Then 'make installkernel' should do exactly what 'make install' does now, including renaming <kernel> to <kernel.old> (whatever the actual name of <kernel> is). It should do the magic in /usr/obj instead of /usr/src (allowing a total RO /usr/src) and ideally not require a complete set of sources, unless there is a dependency like the binutils boundary. By following this strategy, we can tell our users ALWAYS use the new targets, and totally deprecate the old method. This will buy us several things. First off, it will help alleviate the hellacious confusion that's being caused now by "when do I _really_ need to use the new targets????" in -stable. It also will buy us a lot more flexibility in changing the magic behind the scenes while allowing us to present a consistent UI to our users. I would suggest the following for handling options. There should be a "-DCLEAN" (or whatever) knob for doing what config -r does now. The kernel config file can be specified in /etc/make.conf, with the command line overriding it. The default kernel name should be kernel, with the ability to override it with makeoptions in the config file, and on the command line. I would also suggest splitting the KERNEL define into KERNELNAME and KERNELCONFIG, to allow for maximum flexibility. http://www.freebsd.org/cgi/query-pr.cgi?pr=17698 also has some interesting ideas on how to handle buildling multiple kernels with the same "buildkernel" command. Marcel is currently looking into this. HTH, Doug -- "Live free or die" - State motto of my ancestral homeland, New Hampshire Do YOU Yahoo!?
