This is an interesting question. As far as I know, there is no general answer (something like 'dumpisofs' or similar). > Given a bootable ISO9660 image (rescue Linux in my case), I want > to compose another image with more files (my partition image > being created with the tools) ? How do I extract the bootable > image ? Does it appear somewhere among the mounted files ? Usually it does. It depends on the type of image. If it's a floppy image (which is common), it will probably be some file under /boot or something like that, which can be usually identified by its size (which is exactly 1440KiB). If it's a "no-emulation" image, e.g. isolinux, I don't know of means to extract it, but it probably has all its configuration in normal files on the CD, and the image itself you can find otherwize (e.g. isolinux is part of syslinux - google). You can also try to add files with mkisofs's -M option. I didn't try this and do not know if it will remain bootable. If you try, please report. > How do I restore the right flags for 'mkisofs' to create similar image ? usually '-b image'. E.g. if you have under dir1 the tree of the CD, and inside it a directory 'boot' with image 'bootroot.img', do, inside dir1, something like: mkisofs -b boot/bootroot.img -r -o ../dir1.iso . > Will it be bootable on DVD-R as well ? I guess so, but didn't try. Again, would love to hear reports. -- Didi ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
