You can use `make -jN stage` to build multiple platforms faster but do
|
||||||
|
*not* `make -jN stage rsync` as this will start deploying before the
|
||||||
|
builds are all complete. That's because we want the rsync target to be
|
||||||
|
able to deploy subsets. Instead do: `make -jN somethings && make rsync`.
