And make sure you do a "custom" install of RH and specify the partitions
explicitly yourself. Even a "workstation" will probably damage Mandrake.

If your system is partitioned you can share /home and /tmp if they are
mounted filesystems. /, /usr and probably /var should be separate. You
can share swap.
