Containers recovery after snap channel switch

[stgraber (Stéphane Graber)]

Yeah, most likely those wouldn’t have been mounted before LXD was started, anything after that would not propagate into the mntns.

LXD import not working

nsenter -t $(cat /var/snap/lxd/common/lxd.pid) -m will get you in the namespace. You can then use something like mount -t zfs dataset /var/snap/... to mount it. Normally mounting from outside the snap is propagated inside the snap but there are some cases where this unfortunately isn’t true.
