[Bug 1582394] [NEW] [16.04, lxc] Failed to reset devices.list on ...

[TJ]

Public bug reported:

This seems to be identical to Bug #1413193 which affected 15.04 and was
marked Fix Released.

On a 16.04 host with a 16.04 container:

$ lxc-create -t download -n vpn01 -- -d ubuntu -r xenial -a amd64
$ lxc-start -n vpn02 -d

the container syslog shows repeated instances of "Failed to reset
devices.list on ..." and continues generating such messages:

$ grep devices.list .local/share/lxc/vpn01/rootfs/var/log/syslog
