You mean to cause proper paths in CONFIG.SYS with a new drive letter? Okay but this already doable with some script magic: all CONFIG.SYS changes are done from RPM install/uninstall scriptlets using a cube macro, so one can query scriptlets of all installed RPMs via the rpm -q interface and reinstall those that use cube. Won't be fast perhaps, but fully automated.
Of course, the cube macro may be tweaked to additionally main a file containing a list of all packages that change CONFIG.SYS to speed up the reinstall operation. This is something to think on.
