[gentoo-dev] problem making a bootable gentoo CD-Rom

[Francis]

Hi all,

I would like to create another gentoo live CD. In fact, I want to create a 
cusomized version of the basic live CD, with more files, in order to add 
distfiles and portage-20030422.tar.bz2 on the CD-Rom.

I burned the CD-Rom with mkisofs+cdrecord, with this mkisofs command:

mkisofs -o /root/gentoo-perso.iso -J -r -V "gentoo" -b isolinux/isolinux.bin 
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table . 

I put the exact isolinux directory (from the original live 1.4rc1 CD), and 
other files.

I have a problem when I try to burn this CD-Rom bootable:
I have the gentoo logo on my screen, but these error message:
Loading gentoo....
Could not find ramdisk image: initrd.1024

The file is present in /mnt/cdrom/isolinux/initrd.1024.
The same operation worked with Mandrake 9.1...

any idea ?
regards

Hi !

Can you show us the content of your isolinux/isolinux.cfg file ?

Hi,

I made a new test, but I had the same problem. I have an interesting 
information:
initrd.800 is found, and initrd.1024 is not. I suppose the problem comes from 
the 4 letters in "1024", that does not respect the 8.3 names. You are right. 
I will rename files, and it will work. I don't know how the official gentoo 
live CD is build in order to work with long filenames.

Thanks
regards
