[lxc-users] lxc-start-ephemeral mistakenly using zfs?

[Dan Kegel]

Hi all,
on ubuntu 17.10, I'm having trouble getting lxc-start-ephemeral to work...
it seems to mistakenly think it needs to use zfs.

$ strace -o grog -f lxc-start-ephemeral --orig rbb-ubu1710-2-ubu1710
--name fred -- /bin/sh ls
lxc-start-ephemeral is deprecated in favor of lxc-copy

setting rootfs to .%s. /var/lib/lxc/fred/rootfs
The container 'fred' failed to start.
$ grep zfs grog
20660 execve("/bin/sh", ["sh", "-c", "zfs list 2> /dev/null"], [/* 25
vars */]) = 0
...


I don't recall every giving lxc any hint of any sort that it should use zfs,
so why is it trying?

/var/lib/lxc/rbb-ubu1710-2-ubu1710/config contains no mention of zfs
(see below).

Did I miss a memo?
