You're not going to get a lot of warm fuzzies at that level. They're making something for the distributions to leverage rather than everyone having their own free for all.

If os-prober isn't finding your CentOS install, a GUI boot manager wouldn't either. I suggest filing a bug and attaching the following; > In fact when run grub2-mkconfig then os-prober finds other Linux ionstallations. It is the installer that does not finds them. Perhaops it does not run os-prober or os-prober fails silently because it lacks some file it needs or because mount of other partitions fails when run under the installer. > existing grub.cfg > grub2-install --debug /dev/sda #this will reinstall GRUB, but produces very verbose output that should be captured to a file and attached > bash -x grub2-mkconfig #this will show some light debug output for the script that creates grub.cfg without overwriting the existing grub.cfg > > The results from this script: > > http://sourceforge.net/projects/bootinfoscript/ > > Run that either in CentOS or Fedora.
