[systemd-devel] Systemd-nspawn -- Canot add interface to container

[James Lott]

Shame on me for not spending more time trying to figure this out before 
responding. Please ignore my previous sad plea for help, I understand fully 
now exactly what you're saying, and was able to successfully move the phy0 
interface into my container.

At this point, my challenge is going to be coordinating the movement of this 
interface within a service file, so I don't need to do it manually when 
starting the container... but I suppose I can write an ExecStartPost script 
which can manage this.

Thanks again for all your help!
