Comment 29 for bug 1611078

Is there a regression here? Launching a Yakkety 16.10 LXD container fails to install the core snap, fusermount cannot do its magic:

root@e:~# snap install core
error: cannot perform the following tasks:
- Mount snap "core" (1577) ([start snap-core-1577.mount] failed with exit status 1: Job for snap-core-1577.mount failed.
See "systemctl status snap-core-1577.mount" and "journalctl -xe" for details.
)
