From GalliumOS Wiki
GalliumOS nightly builds are available for download from our integration server.
Nightly builds are not tested, and might be completely nonfunctional!
They might also contain updates that are important to you.
In general, we recommend that you stick to official releases and updated packages, except in rare circumstances where you need specific functionality or bugfixes, or if you are helping test new software updates.
