[systemd-devel] nspawn: premounted /dev, /proc, /sys ?

[Seraphime Kirkovski]

Hello systemd devs !

Having nspawn run containers with premounted /dev, /proc and /sys has 
been on the TODO list for a while now. I'm willing to write a patch for 
this as my recent usage of nspawn requires it in some sense.

Before starting, I would like to know if there isn't already someone 
working on it in the community.

And more importantly I would like to know if an nspawn capable of 
running containers with premounted and prepopulated /dev, /proc or /sys 
would be an acceptable thing to have in upstream systemd. I'm asking 
this because I saw recently 8274e40d8:

	nspawn: reword notice when /dev is pre-mounted and populated 
	(#4971)

where a new error message suggests it is possible to use a premounted, 
but not prepopulated /dev. I don't quite understand why using 
a premounted, but unpopulated /dev would be useful, but the message let 
me think that the opposite is probably undesired.

Cheers,
