Adam, The entire container is not readonly. Just /sys, the mount point for /dev/.lxc/sys. I choose another charm (neutron-api) to look at, /sys on that unit is readonly as well. Is that normal?
What would be different in my config? My Xenial install is on a VM, but I’ve been running that way for weeks. I did have the openstack-novalxd bundle successfully deployed on it previously using juju 2.0_rc1. -Heather > On Oct 20, 2016, at 11:30 PM, Adam Stokes <adam.sto...@canonical.com> wrote: > > Odd it looks like the container has a read only file system?
