Thank you fo your answer.
What a pity
I too discovered that isodebug should belong to cdrtools. But in gentoo, the cdrtools ebuild does not produce any isodebug. There are no USE-flags to switch on either, so I can't tell why it's missing. Maybe this should be reported as an ebuild bug?
However, I managed to extract the information I needed from the ISO like this:
Code: Select all
bash-2.05b# grep --text mkisofs install-x86-minimal-2004.1.iso
mkisofs 2.01a24 -J -R -l -o install-x86-minimal-2004.1.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -z livecd-stage2-x86-200404131`DOCùISOLINU2RR_MOVEDúZISOFaHANDBOOKVAACRAID?ACT2000WAIC7XXX
bash-2.05b#
This shows how the iso was made, and that is kind of everything I wanted to do with isodebug. (I think)
