Upsalter was designed to create a rootfs image, possibly with a salt-minion installed that you can deploy anywhere.
It will build a rootfs image of your favorite distribution with salt installed
./bin/upsalter chroot:build centos 6 centos6-salted.tar.gz
It will deploy your chroot package to a remote server and start salt-minion.
./bin/upsalter chroot:deploy centos6.tar.gz user server directory my-container-id
