A couple of bugs I reported in Mandrake Forum on Jan 27th, and at least the top one is still broken:
If you want to do an upgrade with mdkinst, either normal or packages installed only, and you have had the HD partition mounted in your running install (fstab) that has your /Mandrake/RPMS directory in it, mdkinst gives an error: 'An error occurred. Mount failed: Device or resource busy', and you can't go any further. You can't even Exit properly, it just keeps bringing back this error dialog (actually the installer will eventually crash if you keep clicking on Exit). You have to go back and *edit out* the HD partition in fstab that these install files are on, then rerun mdkinst, and then it will work correctly. In other words, it looks like mdkinst is trying to mount this partition twice. Once at the beginning of the install when you are telling it what HD partition the packages are on, and second when it gets to the diskdrake area during the install. mdkinst locks up if you try to format the swap partition in diskdrake. (This may be fixed-- haven't test this bug in a while) -Bill
