Bug 42830 – 2004.0 LiveCD v20040204 - Cant change cd image at all

• Product: Gentoo Release Media
• Status: RESOLVED INVALID

[Description Adam Hewgill 2004-02-24 19:46:02 UTC]

Firstly I burned the ISO onto a CD and noticed that it does not automatically
finialize the CD.  Tested the CD and it works.  Put CD back into drive and
burn multisession (Nero) to add stages to CD and then on boot crashes with
infinite error messages:

kmod: failed exec /sbin/modprobe -s -k binfmt-464c, errno=8

I dont know if this is because I burned the CD in windows or not but I also tried using WinISO to add the stages to the ISO before burning (XIso wouldnt 
work for me)  This resulted in same error.
I tried putting the stages in /stages and in the root of the CD but neither
worked.

:o)

Reproducible: Always
Steps to Reproduce:

Expected Results:  
Booted to command prompt

you cannot edit the iso using another system.
the ISO uses zisofs options, which indicate a compressed ISO filesystem,
Windows DOES NOT support this.  So on boot, you get the BINFMT errors,
because the ISO filesystem does not know it should be trying to uncompress
the executables, etc stored on the cd, hence it cannot recognize the 
binary format (binfmt).  Make sense?

also, just to make sure I'm clear, if you burn the ISO _without_
editing it, it will work, because a windows image writer (nero/easycdcreater)
will write it raw, and not edit it...
Appending to a cd (multisession) will rewrite the index, and pretty much
override the bits that are necessary to tell it that it should be expecting
zisofs data.
