Following the wiki's advice, I installed ubuntu-zfs. However, once everything installed correctly, and I tried installing another application via apt-get, I get a weird issue with my sudoers file:

max@host:~$ sudo apt-get install deluge deluge-web
sudo: /etc/sudoers.d/zfs is mode 0644, should be 0440
>>> /etc/sudoers.d/README: /etc/sudoers.d/zfs near line 18 <<<
sudo: parse error in /etc/sudoers.d/README near line 18
sudo: no valid sudoers sources found, quitting
*** glibc detected *** sudo: double free or corruption (!prev): 0x08909d08 ***
======= Backtrace: =========
....

Why has zfs messed with the sudoers file? I can post the backtrace if needed.
