Comment 3 for bug 1829047

I ran into this bug when upgrading from 18.11 to 19.04 charms. I juju set sysctl="" and that resolved the issues.

Checking for container=lxc in /proc/1/environ seems straightforward enough. If possible a backport to 19.04 would save (me) some work and I suspect problems for others who haven't upgraded yet.
