Dependencies prevent usage with zfs-dkms rather than zfs-fuse

[Francis Chin]

I'm using ZFS on a fresh install of wily using zfs-dkms (from the standard ubuntu wily repository, I'm not using the zfs-native PPA) and trying to install zfsnap - however, apt-get will suggest removing zfs-dkms (and others) in favour of installing and using zfs-fuse.

The dependencies for zfsnap name "zfs-fuse" but also alternative packages "zfs" and "zfsutils" which are not available - perhaps these are meant to be "zfs-dkms" and "zfsutils-linux"? I don't think zfsnap really requires the FUSE version of ZFS rather than the kernel module version.

Steps to reproduce:
1. On 15.10 wily, check you have zfs-dkms and zfsutils-linux installed, and not zfs-fuse
2. sudo apt-get install zfsnap

Result:
[...]
The following packages were automatically installed and are no longer required:
  libnvpair1linux libuutil1linux libzfs2linux libzpool2linux spl spl-dkms zfs-dkms zfs-doc
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
  zfs-fuse
Suggested packages:
  nfs-kernel-server kpartx
The following packages will be REMOVED
  zfsutils-linux
The following NEW packages will be installed
  zfs-fuse zfsnap
