Package: initramfs-tools Version: 0.120 Severity: normal Hi. When / is on btrfs, then /usr/share/initramfs-tools/hooks/fsck tries to include /sbin/fsck.btrfs into the initramfs; fsck.btrfs is however in /bin (and included by btrfs-tools' initramfs hook). So the warning is misleading (as a fsck for btrfs IS installed). Could you somehow work together with the btrfs-tools maintainers to reseolve this? Thanks, Chris.
