tags + help affects - yaboot-installer thanks Current os-prober implementation won't detect system folders in various languages in international versions of Mac OS. Assembling a list of all system folder names may be one way to go.
Another way could be to do MacOS X probe in a shell script first, and if it yields nothing, run a small binary executable which would check blessing status. UInt32 finderInfo[3] has non-zero value if a blessed MacOS 8/9 folder is located on a HFS+ volume (HFSPlusVolumeHeader struct). UInt32 drFndrInfo[0] has non-zero value if a blessed folder is located on a HFS volume (HFSMasterDirectoryBlock struct). Make sure no Yaboot, Quik, or Grub is located on the blessed volume. HFS wrapping details are described in Apple Technical Note TN1150.
