[systemd-devel] configuring nspawn private network (mtu & mac)

[Ede Wolf]

Hello,

I am having two container connected via private network to a bridge with 
a mtu of 8k.

However the .nspawn generated interfaces have the default mtu of 1500. 
And while I can manually adjust the mtu to 8k using the ip link command, 
I am wondering, wethere there is a way to specify the mtu right in first 
place?

Having "MTUBytes=8192" inside the containers host0.network does not do 
the trick. While the mtu inside the container is shown as 8k, the hosts 
still lists the interface with an mtu of 1500 - and this of course 
creates problems.

And, while we are at it, is there a way to specify the mac as well?

Thanks

Ede
