Hello. The document SMM:1 describes how to separate
/usr/src/sys/compile directory from /usr/src. (see
/usr/share/doc/smm/01.setup/paper.ascii.gz "6.6. Recompiling and
reinstalling system software".) I modified config(8) to support this
facility.
In FreeBSD, steps to separate are:
1. Make `obj' directories. (At the first time only)
1.1 # mkdir /usr/obj/sys
1.2 # mv /usr/src/sys/compile /usr/obj/sys
1.3 # mkdir /usr/obj/sys/libkern
1.4 # ln -s /usr/obj/sys/libkern /usr/src/sys/libkern/obj
(1.3 and 1.4 are done by `make obj' in /usr/src)
2. Build a kernel.
2.1 # cd /usr/src/sys/i386/conf
2.2 # config KERNEL
2.3 # cd ../../compile
2.4 # rm machine; ln -s /usr/src/sys @; ln -s /usr/src/sys/i386 machine
2.5 # make all install
My modification is very simple. In the step 2.2, `config -l KERNEL'
will do step 2.4 automatically. How about this idea?
Thank you.
