+#
+# (2) the partition table of all disks.
+# this partition table can be used to format another disk of
+# the same size. this can be handy if using software raid and
+# you have a disk go bad. just replace the disk and partition it
+# by running "sfdisk /dev/sdb < partitions.sdb.txt"
+# (MAKE SURE YOU PARTITION THE CORRECT DISK!!!)
+#
+# (3) hardware information.
+# a simple report is generated of the kernel modules, the devices,
+# and the model of the hardware which 'discover' is able to detect.
