Niltze, all-
Building kernel the 'Debian way':
Replaced abi string at debian/config/defines (from default value of 2)
to a more descriptive string:
[abi]
abiname: reiser4
(guided by hint that debian devs sometimes set abiname string "trunk")
Everything builds beautifully, especially UDEBs for modules/kernel
like couple shown below:
[...]
3.7M kernel-image-4.0.0-reiser4-amd64-di_4.0.8-2_amd64.udeb
34M linux-image-4.0.0-reiser4-amd64_4.0.8-2_amd64.deb
Once kernel build is finished, I place the approxiamately 54 generated
UDEBs at the installer/build/localudebs directory and modify
installer/build/config/amd64.cfg
# The version of the kernel to use.
## KERNELVERSION = $(LINUX_KERNEL_ABI)-amd64
KERNELVERSION = 4.0.0-reiser4-amd64
## KERNELMAJOR = 2.6
KERNELMAJOR = 4.0
KERNELNAME = vmlinuz
save modifications and execute command:
make build_netboot-gtk
The resulting netboot d-i iso image uses the custom kernel to start
the Debian installation -- as can be verified by executing in an
alternate shell: uname -a:
Linux [host] 4.0.0-reiser4-amd64 #1 SMP Debian 4.0.8-2 (2015-07-22)
x86_64 GNU/Linux;
nevertheless stops at 'no kernel modules were found' and thus d-i can
not proceed further to install custom built kernel with reiser4
built-into-the-kernel support -- much less to detect/format a
disk/partition win Reiser4.

Stuff you put under localudebs/ is only used to replace/complement
what's in the archive if something pulls it in. You probably want to
add some packages to some list under build/pkg-lists.
There's also a monolithic target you could use to bundle almost
everything into your image. This is a bigger hammer though.

According to the Debian Installer online reference <
https://wiki.debian.org/DebianInstaller/Modify/CustomKernel > it
suffices to place all the *.udebs at build/localudebs directory.
There is no other example and/or guidance on how to go about
populating, say (from build/README)
* Anything listed in pkg-lists/local and pkg-lists/*/local is included in
the image that is built. This is to provide an easy way to add extra
udebs to a test image.
Thus, there is no indication where the installer will be picking up
the full 34M DEB linux-image-4.0.0-reiser4-amd64_4.0.8-2_amd64.deb so
as to be an option during the installation procedure.

I am making progress as I have built UDEBs for mkfs.reiser4 and fsck.reiser4:
mkreiser4-udeb_1.0.9-2_amd64.udeb
reiser4progs-udeb_1.0.9-2_amd64.udeb
which in turn I have also placed under build/localudebs.
Prior to d-i's: make build_netboot,
I have also specified at build/pkg-lists/netboot/amd64.cfg
mkreiser4-udeb
reiser4progs-udeb
...
ext4-modules-${kernel:Version}
jfs-modules-${kernel:Version}
the above ext/jfs module UDEBs were generated automatically by
building kernel the 'Debian way', but...
QUESTION:
How do I specify -- prior to building a reiser4-patched kernel the
'debian way' -- a directive to build the *extra* reiser4 module UDEB?
Before/After specifying reiser4 as a module in .config (i.e., make -C
debian/build/build_amd64_none_amd64 menuconfig ), I have tried adding
the reiser4 directive to the debian/rules.gen inside the kernel tree
source -- still it does not generate a reiser4 module UDEB.
It seems the reiser4 module is needed for the d-i to format and
recognize reiser4. Note that by Ctrl -Alt -Fn I am able to go under
the installer shell and format in reiser4 and subsequently modify the
/etc/fstab from an di-JFS-formatted partition --using nano;
subsequently the installer will continue the installation of Debian
into reiser4-formatted media *unaware* that it was *tricked*.

Thanks in advance for any insight.

Look under debian/installer in the linux source package and read the
kernel-wedge documentation.

After some effort, I was successful in creating the *extra*
reiser4-modules UDEB:
reiser4-modules-4.1.0-2-amd64-di_4.1.5-2_amd64.udeb
for
kernel-image-4.1.0-2-amd64-di_4.1.5-2_amd64.udeb
I included relevant directives in the build/pkg-lists/netboot/amd64.cfg, thus:
[...]
fat-modules-${kernel:Version}
ext4-modules-${kernel:Version} # Without this, d-i won't know about Ext2/3/4
jfs-modules-${kernel:Version} # Without this, d-i won't know about JFS
reiser4-modules-${kernel:Version} # Thus I thought this would allow
d-i to *know* about reiser4
mkreiser4-udeb # This provides mkfs.reiser4 to d-i
reiser4progs-udeb # This provides fsck.reiser4 to d-i
[...]
After "make build_netboot" finished and tested the installation mini.iso:
lsmod: shows reiser4 module (which I loaded manually from the d-i shell utility)
https://pbs.twimg.com/media/CNKHCDyUkAA0lic.png:large
However d-i partman still does not recognize the reiser4-formatted partition:
https://pbs.twimg.com/media/CNKHCDmUcAAc6pT.png:large
Which means, I now should attempt to create a partman-reiser4 udeb for d-i?
Thank you for all your help and I appreciate your hints and suggestions.
Best professional Regards.
