I was wondering about that when I saw your PR; actually, I think that the current FreeBSD kernel building infrastructure is quite sufficient for what you want to do, without any more modifications. To use different make.conf settings, you have three options: - use the same make.conf file, but with .ifdef FOO ... .endif blocks, containing per-host configuration variables; - use a single simple make.conf file with .ifdef FOO / .include make.foo.conf / .endif blocks, with different make.foo.conf files for the different hosts; - set the (slightly underdocumented) __MAKE_CONF variable to a different value. To use different kernel configs, just set the KERNCONF variable to the value you need. The object directory is set according to the KERNCONF value - if you have different kernel config file names, you will have different object directories. Why do you need different source trees and kernel config dirs? I see no problem with keeping all kernel configs for the same version of FreeBSD in the same src/sys/<arch>/conf/ directory, or at least keeping symlinks to different files in the same src/sys/<arch>/conf/ directory. Different source trees - if you have a source tree checked out to use for building the kernel, what is stopping you from invoking the 'buildkernel' target from the corresponding src/ directory, the one directly above the sys/ directory? Of course, I am probably overlooking some aspects, or missing information about your particular configuration. Still, I believe that for most configurations, the already-provided variables and build infrastructure are quite sufficient.
