Ubuntu also maintains the package, and I did not find it in Debian repositories. I think it's also worth mentioning that these snapshots were created by the do-release-upgrade script using the package directly, not as a result of the apt configuration. Meaning if you do not want a snapshot taken prior to upgrade, you have to remove the apt-btrfs-snapshot package prior to running the upgrade script.

Yup. Everyone in their own way, plus all the home-brews.
