New description:

 We have a lot of fat docker images for postgis, geos, geos-php which was
 eating up a lot of space so was down to 4 GB on the partition I had
 alotted for lxd zfs.

 That said I created a new 250GB disk zfs partition and moved debbie docker
 to that.

 I'll write the steps in

 https://git.osgeo.org/gitea/postgis/postgis-servers

 once I've figured the best place to put it, for now here are my scribbled
 notes:
