Hi, all. We've make custom isos of CentOS and having trouble during the installation. Here's what we did : Add our rpms to CentOS/RPMS Add a folder of scripts and two kickstart files to the base directory run "pkgorder /path/to/base i386 CentOS > /tmp/foo.txt" run "genhdlist --fileorder /tmp/foo.txt /path/to/base" rerun the pkgorder command Add a custom group to CentOS/base/comps.xml run "buildinstall --pkgorder /tmp/foo.txt --version 4.2 --product "CentOS" --release "BAR_V1" --discs "BAR" --prodpath CentOS --comp BARv1 /path/to/base" change isolinux/isolinux.cfg to add two labels, one for each ks file run "mkisofs -o foobar.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -R -J -v /path/to/base" to generate the DVD iso. This iso works fine when we burn it to dvd and install from it but when we boot from DVD and select the kickstart file that installs from a USB drive, we get the following error : "trying to mount already-mounted image!" Could anybody explain why ? Emmanuel
