Dockerfile

# **** NOTE ****
# This doesn't yet yield a usable docker image.  I can't seem to get libzfs to initialize,
# even if I bind /dev/zfs and /dev/zvols in.  I'm including it anyway because it took time
# to get it to this point and I may return to the struggle at some point in the future.

# Start from a Debian image with the latest version of Go installed
# and a workspace (GOPATH) configured at /go.
