The media is ethernet, don't know if it is possible over wifi.

Or is it so that you don't really want netbooting, instead you want 
to boot from some local media as in the "netboot cd" procedure ?

As you wrote you have a lot of similar installations, I suggest you 
make a model fs and copy (dd) it to the new disks. And then using
a selfmade script that sets up the config.

The easiest way is to use a sata docking station and do all the disks
in one run. This is one example:

Not tried that.

It is a while since I did this, so this info might be old.

To netboot, you go into the "bios" and tell it to boot over pxe;
perhaps it already has it as boot alternative.

On the "server" side, you have a rarp/bootp/dhcp server and a tftp server, 
possible also a nfs server.

The usual procedure is to boot a pxebootloader which then boots the 
kernel. Booth thoose is to be available on a tftp server.
The kernel has to be specially prepared with mknbi.

The kernel then mounts a nfs fs as root.

This is about which media and how
can be used to netboot Devuan at the installation time.

AFAICS the available installer is not capable of setting up networking
without the installation CD iso at hand.
This means it cannot proceed if netbooted.

Did you succeed to install current Devuan with netboot?

Thanks

I have done some pxe booting and install in the past.
What do you need help with ?

[DNG] netbooting Dev1

2020-01-08 Thread dal
Dear all,

I am facing a two-faceted challenge:

One is to make a very minimal, stable (reproducible in the sense of the same 
versions of the same package set) OS installation.
Two is to install from the network with netboot (pxe/efi).

Debian has no installer which out-of-the-box could access the contents of an 
installation CD over the net, but the above is attainable by merging and 
tweaking the cd- and net-boot initrds, without actually building the installer 
from scratch. We tested this.

Unfortunately Dev1 has no supported way (?) to be installed without 
pre-supplying a 300+ MB iso image to the target machine in some out-of-band 
way, like physically on a CD.

An ideal solution would be to let the cd-installer contain the network-related 
tools inside the initramfs (like Debian netboot media does) and initialize the 
network before trying to access the data from the CD. Then it would be easy for 
us to replace the CD with secured remote data, which we have done with Debian. 
Otherwise, even a plain Debian-like netbootable installation media would do.

Is there any practical way to reliably acquire or produce such a media, short 
of learning to be a Dev1 developer?

A related question has been asked by someone else on 
https://dev1galaxy.org/viewtopic.php?id=3197 without any positive answer.

The outfall can decide the OS for hundreds of coming installations, which is 
why I am asking the question before giving up and taking the pain of systemd 
brought along by Debian.

Regards
/D
