Actual behavior

INFO[0029] Running: [/bin/sh -c npm install] 
{{...some NPM output ommited...}}
added 1635 packages from 1037 contributors in 15.068s
INFO[0044] Taking snapshot of full filesystem...

INFO[0060] Saving file . for later use                  
error building image: could not save file: read /dev/agpgart: invalid argument

Expected behavior This should simply work as the same Dockerfile used with docker works.
