Hi Patrick,
The salt ebuild has been refactored to remove the tests and modules that require dev-python/boto, and the mask has been removed.Salt has a lot of users, and it would be doing them a disservice to remove it from the tree.
Salt is not trivial to distribute, because upstream wants us to run curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io Thank you for saving the salt ebuild. It really has a lot of users. -- Best, Jonas
