Public bug reported:
Symptoms
--------
If an lxc container named *mycontainer* runs, it is not accessible using
name *mycontainer.lxc*.
Causes
------
The lxc1 package provides the lxc-net.service which launch a dns-masq
process to act as dns providing name resolution to local lxc instances
using the .lxc domain.
This DNS is however not declared to systemd-resolved, and so .lxc names
do not work on a standard ubuntu install.
Proposed solution
-----------------
The lxc1 package should provide a /etc/systemd/resolved.conf.d/lxc.conf
with the following content::
[Resolve]
DNS=10.0.3.1
Domains=~.lxc
DNSSEC=false
