Hi,
here is my "real" problem.
(1) Using Debian sid, try building grml64-full using the command line:
sudo grml-live -A -V -u -e ~/grml-remaster/grml64-full_2017.05.iso -s stable -c DEBORPHAN,GRMLBASE,GRML_FULL,RELEASE,AMD64,IGNORE,SNAPSHOT -r "test20170830" -g grml64 -o ~/grml-remaster/tmp
This results in tmp/grml_isos/grml64_0.0.1.iso being generated.
(2) dd this iso to a LV. Configure a new VM with a CDROM drive and connect this drive to the LV containing the ISO. Boot.
Boot works.
(3) Try to re-build the grml .iso from within grml using: grml-live -V -e /dev/cdrom -o output/
this emits warnings during the build process about missing EFI files, ending in "xorriso : FAILURE : Cannot find path '/boot/efi.img' in loaded ISO image" (full log in exhibit A).
(4) configure the same VM to boot from a released grml64-full.2017.05 iso
(5) try rebuilding the grml.iso file with the same command line: grml-live -V -e /dev/cdrom -o output/
(6) see the build succeed (exhibit B).
What am I doing wrong when building grml64_0.0.1.iso so that it cannot self-reproduce, while the released grml64-full.2017.05.iso can? Any hints?
Greetings Marc
