Looks like they do, otherwise I guess that they would not be able to set upthe 
tinc VPN from the beginning. However, I have noticed that the mechanism forthe 
dns queries in the system is not as simple as it used to be. I have a systemd 
resolved daemon in the middle that is said to do caching. I am now wondering if 
the resolution from the chroot may be influenced by this (e.g. succeed in case 
the name is hit in the cache, fail in some other case). I am not sure of how 
this hypothesis can be tested.

I will try this.  Thanks,
