Can you describe said shooting of foot? Because... + I still build my kernels that way, because... + config can be given -C to retain the *entire* config file in the kernel, c= omments-and-all, because... + There has traditionally been no knob that can be set during the kernel tar= gets of the top-level Makefile that will enable "config -C" instead of just "= config". We use a version-controlled config file and want lines like "# $Smule: ... $= " retained as well as include lines, etc so we can see hierarchical topology= of the kernel config from a running system in the field simply by running "= config -x $( sysctl -n kern.bootfile ) | less" Thus, I wouldn't even call this a "FreeBSD 4.x [process] of bulding the kern= el" but instead "an alternate proceaa of building kernel" and the people tha= t use it know what they are doing and this there is no foot shooting. NB: I actually use "config -C -g" for full disclosure. --=20 Devin > On Oct 29, 2017, at 1:25 AM, Eitan Adler <eadler@FreeBSD.org> wrote: >=20 > Author: eadler > Date: Sun Oct 29 08:25:31 2017 > New Revision: 325097 > URL: https://svnweb.freebsd.org/changeset/base/325097 >=20 > Log: > Update UPDATING >=20 > - Remove FreeBSD 4.x of building the kernel. > While it might technically work, it is better to > document the 'correct' way than how to shoot oneself > in the foot >=20 > - Remove reference to CVS -P for src. >=20 > Modified: > head/UPDATING >=20 > Modified: head/UPDATING > =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D > --- head/UPDATING Sun Oct 29 08:17:03 2017 (r325096) > +++ head/UPDATING Sun Oct 29 08:25:31 2017 (r325097) > @@ -1843,21 +1843,6 @@ COMMON ITEMS: > make installkernel KERNCONF=3DYOUR_KERNEL_HERE KODIR=3D/boot/testkernel= > nextboot -k testkernel >=20 > - To just build a kernel when you know that it won't mess you up > - -------------------------------------------------------------- > - This assumes you are already running a CURRENT system.
