I believe that having a netboot option in Devuan is very important,
and it would not require much effort, indeed. In the past I have used
PXE boot many times to install Debian on headless servers (I still
have dhcp and tftp configured for that in my laptop), and it always
worked like a charm. We definitely ought have that option, despite
real metal servers will unavoidably become an even smaller minority in
the server landscape :)

Ok, but will that initrd/vmlinuz ask for a cd or will it ask for a URL
where the installer packages can be found? Or is the trick done by the
--method=http?

Anyway, Debian has such an option and I think it would be very valuable
if such an initrd.gz/vmlinuz would be available from the Devuan
mirrors. This will make Devuan being available through many PXE boot
servers accross the planet.

That said, I think it should be part of the Devuan distribution. Each
time a new version sees the light, the appropiate vmliz/initrd.gz pairs
should be generated for each available cpu.

Try it yourself and see how it works when you start one of these kernels:

amd64:

wget -N 
http://ftp.debian.org/debian/dists/jessie/main/installer-amd64/current/images/netboot/debian-installer/amd64/initrd.gz

wget -N 
http://ftp.debian.org/debian/dists/jessie/main/installer-amd64/current/images/netboot/debian-installer/amd64/linux

i386:

wget -N 
http://ftp.debian.org/debian/dists/jessie/main/installer-i386/current/images/netboot/debian-installer/i386/initrd.gz

wget -N 
http://ftp.debian.org/debian/dists/jessie/main/installer-i386/current/images/netboot/debian-installer/i386/linux

No need for cd's, no need for USB sticks, just a network connection.

Hi Richard,

It depends on your purposes. For example, an initrd.gz taken from a 
netinst image will not be valid for a live system, because it doesn't 
contain the live-install udeb package, which is essential for a live image.


But you can build your own initrd.gz and vmlinuz building debian-installer:

*HOW TO BUILD DEVUAN-INSTALLER*

1) Download the sources:

apt-get source debian-installer

2) Check the build dependencies and install them:

cd debian-installer-201507023+devuan.alpha4
dpkg-checkbuilddeps
apt-get install ... bla bla bla ...

3) Download the udeb packages using debmirror:

debmirror -h ftp.es.mirror.devuan.org \
  --dist=jessie \
  --root=/merged \
  --di-arch=i386,amd64,armhf \
  --section=main/debian-installer \
  --nosource \
  --progress \
  --ignore-release-gpg \
  --method http \
  --diff=none \
  /home/richard/localudebs

4) Customize your *.udeb pcakages, if you want. For example rootskel-gtk.

5) Copy all the *.udeb packages to 
debian-installer-201507023+devuan.alpha4/localudebs and build d-i:


cd build
make build_cdrom_isolinux

The first attempt allways fails. No worries :)

Copy the content of the sources.list.udeb -generated automatically 
during the failed attempt- into a new file named sources.list.udeb.local

In my case, the content of this file is:

# This file is automatically generated, edit sources.list.udeb.local 
instead.
deb [trusted=yes] 
copy:/home/aitor/d-i/debian-installer-201507023+devuan.alpha4/build/ 
localudebs/

deb http://packages.devuan.org/merged jessie main/debian-installer

6) Clean the content generated by the failed attempt and try again:

apt-get autoremove
make build_cdrom_isolinux

The initrd.gz and the vmlinuz will be generated in the dest folder :)

HTH,

  Aitor.

For the moment libsystemd is still in use AFAIK

I already tried that of course :-) But this initrd/vmlinuz will ask you
to mount the cd. Of course I can try to use nextserver or something
like that, but I like the Debian option to use a real network
installer. It will simply ask for the repository to use.

I had thought that it's part of the devuan-baseconf package, but
apparently it's not. So here my sources.list:

--snip--
deb http://de.mirror.devuan.org/merged/ jessie main contrib non-free
deb-src http://de.mirror.devuan.org/merged/ jessie main contrib non-free

deb http://de.mirror.devuan.org/merged/ jessie-updates main contrib
non-free deb-src http://de.mirror.devuan.org/merged/ jessie-updates main 
contrib non-free

deb http://de.mirror.devuan.org/merged/ jessie-backports main contrib
non-free deb-src http://de.mirror.devuan.org/merged/ jessie-backports main 
contrib non-free

deb http://de.mirror.devuan.org/merged/ jessie-security main contrib
non-free deb-src http://de.mirror.devuan.org/merged/ jessie-security main 
contrib non-free 
--snap--

You might want to choose another mirror, or the redirector:
auto.mirror.devuan.org

Depending on your configuration and personal preferences, some ideas
for your /etc/apt/preferences - AFAIK, if you have only devuan/merged
repos in your sources.list, you don't need to assign the "-1" pin to 
systemd-sysv:

Package: libsystemd0
Pin: release o=*
Pin-Priority: -1

Package: systemd
Pin: release o=*
Pin-Priority: -1

Package: systemd-sysv
Pin: release o=*
Pin-Priority: -1

Package: *
Pin: release a=jessie-backports
Pin-Priority: 150

I am not 100% sure, but I think you can use initrd and vmliuz straight 
from the netboot iso:

$ mount -o loop -t iso9660 /path/to/iso /mountpoint

Please correct me if I'm wrong^^

Here's what I have so far:

most from the 64 bit install. added non-free and contrib so far so good

# deb http://us.mirror.devuan.org/merged/ jessie main

deb http://us.mirror.devuan.org/merged/ jessie main non-free contrib
deb-src http://us.mirror.devuan.org/merged/ jessie main non-free contrib

# jessie-security, previously known as 'volatile'
deb http://us.mirror.devuan.org/merged/ jessie-security main contrib 
non-free
deb-src http://us.mirror.devuan.org/merged/ jessie-security main contrib 
non-free


# jessie-updates, previously known as 'volatile'
deb http://us.mirror.devuan.org/merged/ jessie-updates main contrib non-free
deb-src http://us.mirror.devuan.org/merged/ jessie-updates main contrib 
non-free


# jessie-backports, previously on backports.debian.org
deb http://us.mirror.devuan.org/merged/ jessie-backports main contrib 
non-free
deb-src http://us.mirror.devuan.org/merged/ jessie-backports main 
contrib non-free
