#TIL how to add swap space easily on #OpenBSD

1) Create a swapfile made of many many 0's, in the size of how large a swapfile you want, so e.g. for 16gb:
$ dd if=/dev/zero of=~/.swapfile bs=1m count =16384

2) Add it as swap:
# swapctl -a ~/.swapfile

3) For great success, check it out to get warm fuzzy feelings:

$ swapctl -l
Device              512-blocks     Used    Avail Capacity  Priority
/dev/sd2b             17065992        0 17065992     0%    0
/home/puffy/.swapfile   33554432        0 33554432     0%    0
Total                 50620424        0 50620424     0%
