It would be nice if there were instructions published. We need some help
to write, edit, and verify the instructions. Here is a brief run-down
of how to build an upgrade file. Bryan tells me that last time he tried,
this works equally well on Linux as on NetBSD.
IN A NUTSHELL
1 Extract sources.
2 Set environment.
3 Build the first time,
% ./buildupgrade -s <netbsd source directory>
4 Build the second time,
% ./buildupgrade -s <netbsd source directory> -u modules
IN DETAIL
Initial setup:
1 extract the CUWiN, NetBSD, and other 3rd-party sources that
are on the website.
2 create a directory $HOME/scratch-cuw/ (this accumulates all
of the build products, like .o's, executable binaries, etc).
Build an upgrade file for the first time:
An upgrade file is suitable for upgrading a node
using the /sbin/upgrade utility, for example,
% /sbin/upgrade dyoung at 192.168.29.1:staboot-19-Mar-2005.tgz
Here are the steps:
0 Set EXTSRC to the 3rd-party sources path. In csh, use
setenv EXTSRC <path>. In sh, use export EXTSRC=<path>.
1 Change directory to boot-image/ under the CUWiN source
directory, and type
% ./buildupgrade -s <path to NetBSD sources>
This will build the whole NetBSD system, the CUWiN sources,
and 3rd-party programs. Then it will put the whole system
into a file called, for example, staboot-19-Mar-2005.tgz.
The first tie, expect for the whole process to take hours.
(It takes just a few minutes the second time, I promise!)
Build an updated upgrade file:
0 Set EXTSRC, as above.
1 Change directory to boot-image/ under the CUWiN source
directory. List the build stages by typing
% ./buildupgrade -s <path to NetBSD sources> -L
tools
toolenv
makewrapperenv
distrib
metalog
patch
makewrapper
mv-root-home
flash-kernel
extras
users
modules
cuwinize-metalog
install
postinstallenv
upgrade
2 Consult this guide to choose the right stage to start the build:
If you added a user account or an authorized_keys file,
restart at 'users'.
If you updated your entire NetBSD sources, restart at 'tools'.
*** If you modified the sources for a NetBSD
*** app/daemon/utility, restart at 'distrib'. The 'distrib'
*** stage is the slowest by far.
*** If you made modified the kernel sources,
*** or you changed the kernel configuration in
*** boot-image/kernel-conf/cuw_45x1, restart at
*** 'flash-kernel'. This stage is second-slowest of all.
If you added a file to boot-image/extras/, restart at 'extras'.
If you added/modified a file under boot-image/etc-patches/,
restart at 'patch'.
*** If you changed the CUWiN sources or 3rd-party sources,
*** restart at 'modules'. This is the most common case,
*** by far!
3 Start building at the stage you selected in step #2, by
typing
% ./buildupgrade -s <path to NetBSD sources> <stage>
To build more quickly, use -u to skip the 'make clean' step.
That is, type
% ./buildupgrade -s <path to NetBSD sources> -u <stage>
To run in "fast and loose" mode, use -u -o to skip both the
'make obj' and 'make clean' steps. That is, type
% ./buildupgrade -s <path to NetBSD sources> -u -o <stage>
*** Make sure you understand 'make obj' before you use -o.
*** The risks of skipping 'make obj' are outside the scope of
*** this document.
