Changes for FHS compliance. Removed commented out references to ZIP
drives. Added a line to deal with the fact that libata (in newer kernels) maps IDE drives to SCSI device names, but not all rescue distributions use libata. So we have to change the device names from SCSI to IDE, e.g. /dev/sda to /dev/hda. Changed the address for the FSF in the license.
