I have looked through k3b trying to find an option for creating a bootable cd but cannot find one. Can you offer any further help? Thanks again. I've learnt a bit more but need another nudge! you need the -b and -c parameters to mkisofs. for example the command used to generate the isos for gentoo install cd's goes like this: mkisofs -J -R -l -o ../gentoo.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -boot-load-size 4 -boot-info-table -z . Notes: 1. I am not sure if you can specify this under k3b. mkisofs is used in the background by k3b, but how these particular parameters are referenced is unknown to me. 2. You need to figure out what mechanism is being used to boot the CD, ie what files to pass to -b and -c. isolinux is a popular choice. -- Nick Rout [EMAIL PROTECTED] -- gentoo-user@gentoo.org mailing list

Of course, you could mount the iso on a loop and create a new iso from those files. no you cannot, as it is read only, so once you have mounted it it is still readonly. You can however then copy it to a writable file system, make the amendments and mkisofs it back to a new iso. If I create an iso with mkisofs -udf then I am able to mount -t udf -o loop,rw but there is no extra space on the filesystem to add files. I use mkudffs from the udftools package when I need a writable udf filesystem. --- [EMAIL PROTECTED] wrote: You can mount the iso on a loop device and manipuilate it there.

Re: [gentoo-user] adding files to an iso image
Does anyone know of a linux based prog to add files to an iso image? kiso comes to my mind, but I do not know if it can resize/add files to iso files. Best regards ce -- gentoo-user@gentoo.org mailing list

Thanks in advance -- gentoo-user@gentoo.org mailing list An iso filesystem is read only AFAIK but you can append additional sessions if you like. If you want to do it from the shell with cdrecord and mkisofs (app-cdr/cdrtools) then you need the cdrecord -multi and mkisofs -C options (the respective man pages have further details). Of course, any gui frontend will handle the nasty details for you. You can browse through the app-cdr category at packages.gentoo.org. k3b seems to be highly recommended. Zac __ Yahoo!
