You might think that, but in fact the hook shipped with btrfs-tools only copies in /bin/fsck.btrfs if /usr/share/initramfs-tools/hooks/fsck is not executable. It is executable, so this has no effect.
I have checked on current wily with / on btrfs that my initramfs really is missing fsck.btrfs (in either /bin or /sbin). ** Changed in: initramfs-tools (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1483975 Title: update-initramfs complains about missing /sbin/fsck.btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/btrfs-tools/+bug/1483975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
