Comment 11 for bug 1574342

Hi Eric,

I applied these patches, built them in a ppa and then did a clean install of zfsutils-linux from -proposed and then upgraded to the packages in the ppa. However, your patches break the upgrade:

king@ubuntu:~$ dpkg -l | grep zfsutils-linux
ii zfsutils-linux 0.6.5.6-0ubuntu11 amd64 Native OpenZFS management utilities for Linux
king@ubuntu:~$ sudo add-apt-repository ppa:colin-king/zfs-0.6.5.7-lp1574342

I think the problem is the change to the path:

 override_dh_auto_configure:
  @# Build the userland, but don't build the kernel modules.
  dh_auto_configure -- \
- --bindir=/bin \
+ --bindir=/usr/sbin \
    --sbindir=/sbin \
    --libdir=/lib \

..which is causing the zed issues.

It's heading to 9pm UK time, so I'm running out of time to rebuild and test this hypothesis.
