Hi, all I recreate the rhel6.4 iso file, using the mkisofs command: mkisofs -r -T -J -V "rhel_6.4 " -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -x "lost+found" -o /root/rhel6.4-test.iso /home/rhel6.4-test/. but i am failure to install using the rhel6.4-test.iso, because the /lib/udev/cdrom_id can not get to the ID_CDROM_MEDIA_TRACK_COUNT_DATA value, also, the anaconda can not get the iso type, iso9660. what is the track, and is the command mkisofs correct ? could you help me? thanks. _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
