[Swan-dev] disk usage on test machine

[D. Hugh Redelmeier]

I'm looking at disk usage on the machine that use to run "make check".

Large directories in build's home directory (in ascending order of 1K 
blocks):
691316	libreswan
2948256	results
20908400	pool

So "results" is serious (larger than libreswan itself by a factor of 4).

But pool seems to be much large (21G):
828744	nic.qcow2
1261000	north.qcow2
2206732	swanfedorabase.qcow2
2303472	swanfedorabase.img
2542280	road.qcow2
5819596	east.qcow2
5946572	west.qcow2

Is there a simple way to redo the qcow2 files?  I think that every write 
in the VM to these filesystems adds a block and old ones are not recycled.
"qemu-img info" doesn't seem to tell me stats about this.
