What seems to be happening is if you set a reserved_ratio on an image
and grow the image, that ratio is maintained and will stay at that ratio.
When shrinking the image however, mke2fs.conf is referenced and that's
the ratio that gets used.
Is there a reason for this behavior to be inconsistent? I was incorrect
about making new ploop images using mke2fs.conf - it seems they don't -
at least not through vzctl create. It appears to be hard coded at 5%.

This is great.
When you then resize that image though, the stock 5% is put back in
place instead of the 1% that was on the filesystem (or whatever might
be set in /etc/mke2fs.conf).
Is this intentional functionality for some reason, a bug, or something
simple no one has tried before?
