Anyone know how to use createrepo {or is there another tool} to create useful repodata for a mounted dvd.iso image for say fedora core. It seems that while the image includes a toplevel /repodata folder, when it is mounted and yum.repos.d/fedora-core.repo is pointed at the / of the mounted iso image, yum is not happy with what it finds. I have used createrepo folder option to create a new repodata directory and repo one folder above where the iso is mounted, so that the folder is read/write, and the create can succeed. createrepo -o . disc/Fedora/RPMS/ What I find is that primary.xml does not include the relative path from the folder above the new repodata directory, and hence fails. {actually it includes only the filename of the rpm files not any path at all.} folder where iso is mounted: /home/install/software/linux/fedora/core/6/yum/i386/disc location of rpms: /home/install/software/linux/fedora/core/6/yum/i386/disc/Fedora/RPMS writable location: {where yum.repos.d/fedora-core.repo baseurl will point} /home/install/software/linux/fedora/core/6/yum/i386/ What is the appropriate command to generate usable repodata ?
