Now we create a swap partition - 64 MB should be more than sufficient for our Embedded System; 64 MB
means 64*1024*2 = 131072 disk blocks of 512 bytes:

Finally, we dedicate all the remaining space to the root partition:

To make our changes permanent we must write the new partition table to the disk, before we quit the pdisk
program:
Command (? for help): w
Writing the map destroys what was there before. Is that okay? [n/y]: y
hda: [mac] hda1 hda2 hda3 hda4 hda5
hda: [mac] hda1 hda2 hda3 hda4 hda5
Command (? for help): q
Now we can initialize the swap space and the filesystem:
# mkswap /dev/hda4
Setting up swapspace version 1, size = 67104768 bytes
