Re: Towards a customized netinst

[Richard Owlett <rowlett@cloud85.net>]

Thomas Schmitt's post of 09/21/2017 09:47 AM prompted me to rephrase my 
initial post of this sub-thread.


My initial goal is a "thingy" which a human at a terminal would not 
notice any operational difference from netinst.iso on a CD.
This "thingy" would:
  1. *NOT* have any internal assumption of being ISO9660 compliant.
     1a. be recognizable and boot-able by Grub2.
       {Re-reading <https://wiki.debian.org/DebianInstaller/Modify/CD>
        after reading
< 
http://ftp.nl.debian.org/debian/dists/testing/main/installer-amd64/current/images/MANIFEST>
        suggested at least one reason I could not boot the resulting
        partition - I needed an appropriate set of initrd/vmlinuz.

        Browsing some Wiki pages indicates I need to read MORE about the
        boot process and os-prober.}
  2. intrinsically assume it will be resident on an ext2 device.

I had been attempting to follow the pattern of "Debian-Installer: How to 
modify an existing CD image - Create copy of the image" 
<https://wiki.debian.org/DebianInstaller/Modify/CD#Create_copy_of_the_image> 
.

Using "tar" instead of "bsdtar" giving an error message that "This does 
not look like a tar archive" was motivation to use xorriso. As Thomas 
Schmitt has pointed out, there are other means. Using it is a better map 
to to my mental image while preventing my mental image clashing to badly 
with reality.
