Having multple kernel sources

[Matthew Dillon]

:
:This patch lets you set a KERNEL_SOURCE variable in /etc/make.conf or on the
:command line and the the kernel source you have specified will be build.
:
:The kernel directory you specify must exist inside your src directory. It
:defaults to KERNEL_SOURCE=sys/ if nothing else is specified.
:
:I would just like to know what you people think, is it even needed?

    I don't think it's quite this simple.  Makefile's all over the source
    and system trees use "../.. ...../sys" sequences to get to 'sys'.

    I like the idea in concept, but it might wind up being too messy to
    implement.
