Package: btrfs-progs Version: 4.4.1-1.1 Severity: serious To conclude the btrfs-tools to btrfs-progs rename, ftpmasters need to be contacted to remove btrfs-tools-udev from the archive for unstable and testing. When I discussed the rename with the D-I team, they said a btrfs-tools-udev dummy package was not useful. Debian-cd and partman-btrfs in testing and unstable will not break when btrfs-tools-udev is removed, because they've been patched to use btrfs-progs-udev.
I've tagged this bug as serious, because https://wiki.debian.org/ftpmaster_Removals states "file the bug as an RC bug on the package first, indicating why you think the package should be removed, and asking the maintainer if he/she agrees with reassigning the bug to ftp.debian.org". Thank you, Nicholas
