Package: zfs-fuse Version: 0.7.0-25+b1 Severity: minor As illustrated in for example [1], to have installed both the kernel module and the FUSE versions of ZFS is problematic, as the two are at very different versions (0.7 and 2.1 respectively) and zfs-fuse has limited support for many features added in the interim.
There does, however, currently not seem to be anything preventing doing so by mistake on Debian Bookworm, resulting in unclear errors and potentially an inability to access data by normal means until the situation is resolved by the administrator. Please consider setting up the packages so as to make installing both the OpenZFS and ZFS-FUSE implementations on the same system difficult, possibly by adding mutual Breaks: to the packages in question. NOTE: This bug report probably applies equally to both zfs-dkms AND zfs-fuse; however, I don't see any simply way to lodge the same bug report against more than one package, hence reporting the bug against the package the installation of which risks causing a more immediate problem. (Importing an older pool when using a newer ZFS implementation is generally unproblematic; importing a newer or upgraded pool using an older ZFS implementation can be problematic depending on usage, as illustrated for example in [1] and other messages in that discussion thread.)
