Hi list, Went through Brett Schwarz' excellent article on creating a custom RH8 CD. I needed to build a custom RH9 CD and have done the following, 1. create /var/RH9_BASE directory that directory contains RedHat/base and RedHat/RPMS 2. copied the required rpms in the RPMS directory 3. Modified comps.xml so as to contain only the Core group and listed all my rpms's in that group (Hope this isn't insane) 4. copied all files from /original/redhat/source/cd1/RedHat/base to /var/RH9_BASE/RedHat/base 5. deleted hdlist and hdlist2 6. ran /usr/lib/anaconda-runtime/genhdlist /var/RH9_BASE 7. copied .discinfo from /original/redhat/source/cd1/ to /var/RH9_BASE/ 8. copied bootdisk.img to /var/RH9_BASE/RedHat/images/ 9. did mkisofs -b images/bootdisk.img -o rhtestcd.iso /var/RH9_BASE 10. used cdrecord to make the cd and the installer tells me that it is not a RHL CD !! searched around the archives but could not get something to solve my problems (Maybe i did not look hard enough!!) Please help. Regards, Anoop
