There is a gotcha here. Usually, the default, top level lens of a module
is by convention "lns". In the case of Spacevars, the top level lens is
"lns_simple". Hence, the correct load is this one:

augtool> set /augeas/load/Spacevars/lens "Spacevars.lns_simple"

Or, you can use the special syntax @Module to load the whole module,
then you don't need to worry about the lens name at all, it will load it
from the transform:

augtool> set /augeas/load/Spacevars/lens "@Spacevars"

Cheer,
