Great idea Carl,

rather than the dd I did:
# truncate -s 512M /var/swapfile
# ls -als /var/swapfile
96 -rw-r--r--  1 root  wheel  536870912 Dec 11 02:08 /var/swapfile

The fstab info was very helpful, thanks.  I've now got a 512M swapfile.

I think way back in my original post I said that I'd downloaded a pre-built 
binary for the Pi on the dnscrypt2 github site so I don't need to build go 
any more (at least not at the moment).

But I'm sure the swapfile will save my bacon in the future.

Many thanks for your help,
Scott
