} As far as I can tell, on any version of NetBSD from the NetBSD-5 branch
} point until now (and probably earlier), the simplest command to build
} the system is " -U -O <absolute path to desired objdir> distribution".

     Everything inside /etc/mk.conf is enclosed in .ifdef BSD_PKG_MK.
Did a fresh cvs up immediately before doing this test.  Note that the
first test was done as root. is rev. 1.228.  From visual
inspection, I note that and are used in
determining TOOLDIR.  Those are rev. 1.246 and rev. 1.12 respectively.
BTW, the host is currently:

P4-3679GHz: {261} uname -a
NetBSD P4-3679GHz 5.99.22 NetBSD 5.99.22 (GENERIC) #4: Sun Dec 20 01:24:17 PST 

P4-3679GHz: {250} cd /usr/src
P4-3679GHz: {251} ./ -U -O /usr/obj distribution

The last few lines are:


#    objdir  /usr/obj/tools
===> TOOLDIR path:
===> DESTDIR path:     /usr/obj/destdir.i386
===> RELEASEDIR path:     /usr/obj/releasedir

ERROR: TOOLDIR '' invalid




   252  rm -r /usr/obj
   253  mkdir /usr/obj
   254  chmod 777 /usr/obj
   255  su jnemeth


produced the exact same result.

} By (matt's) code inspection, this should be the case all the way back
} to NetBSD 2.0.

     As shown above, my test showed differently.

} This will put the tooldir in the objdir and even automatically create
} the objdir if it does not exist and the user has permission to do so.

     After the test, /usr/obj contained:


P4-3679GHz: {264} ls -aglR /usr/obj
total 12
drwxr-xr-x   3 root  wheel  512 Jan 24 12:48 ./
drwxr-xr-x  21 root  wheel  512 Jan 24 12:48 ../
drwxr-xr-x   2 root  wheel  512 Jan 24 12:48 tools/

total 8
drwxr-xr-x  2 root  wheel  512 Jan 24 12:48 ./
drwxr-xr-x  3 root  wheel  512 Jan 24 12:48 ../


} I see no compelling reason to put a more complex procedure in the Guide
} though we should probably note that using relative paths on the
} command line is a bad idea.

     In any event, sections 33.1.1 and 33.1.5 (2) are inconsistent in
that the latter has -O -T.  33.1.5 also uses -u, but I left that for
now.  The instructions should be consistent.

     Yet more tests...

     The guide currently says:


33.1.1. Building a new userland

The first step is to build the userland:

$ cd /usr/src
$  ./ -U distribution

33.1.2. Building a new kernel

The next step will build the kernel:

$ cd /usr/src
$ ./ -O ../obj -T ../tools kernel=<KERNEL>

Following 33.1.1, the build blows up complaining about a missing
/usr/obj.  Making /usr/obj and retesting blows up with an invalid
TOOLDIR.  Trying "./ -O ../obj -U distribution" also blows up
with an invalid TOOLDIR.  Trying with an "/usr/obj" also bombs.  Trying
with "./ ... tools distribution" as suggested elsewhere also

     The last couple of changes to are:

revision 1.228
date: 2010/01/13 02:24:06;  author: pooka;  state: Exp;  lines: +6 -3
need object directory for etc/mtree to run distrib-dirs
revision 1.227
date: 2010/01/13 02:18:25;  author: pooka;  state: Exp;  lines: +7 -5
In rumptest, create obj dirs before distrib dirs.  Fail if distrib dir
creation fails.

per clue-by-4 from mrg

Neither nor bsd, have been touched since 2003.

     On a whim, I rebuilt /bin/sh and reinstalled it.  No difference.
