[lxc-users] Inotify does not work in a privileged container

[Simos Xenitellis]

According to this, https://github.com/lxc/lxd/issues/2004
the "Failed to reset devices.list ..." can be ignored.

There should be some additional lines earlier (not shown) that have a
hint towards the real issue.

This "InCronD" is probably using "inotify". Search for "inotify" at
https://github.com/lxc/lxd/blob/master/doc/production-setup.md
to increase the relevant parameters.
