AFAIK modern PIOS versions all use merged /usr, as they are based on 
debian which /usr merged. This means that the /usr directory has to 
reside on the root partition. I usually put my swap partition between 
root and /home partitions. 

I'm assuming your PIOS is running systemd so try looking at 

  man systemd.swap

I remember that on a SYSV init system I think I ran mkswap on the disk 
partition, then added an entry to /etc/fstab like 

  /dev/sda2       none            swap    sw      0       0

and just rebooted.

I tend to use a swap file nowadays.

cheers
Jim
