Hello!
With some help from the kind people on this list, I was able to get my basic
network interfaces up and runnign with systemd-networkd. Now I've moved on to
playing with some slightly more complex setups, and have run into some issues
that as far as I can tell may be bugs (but I'm not quite ready to rule out
user error, so I thought I'd start here before submitting to the bug tracker
;) ).
I have configured a vlan interface to be a member of a bridge via the
appropriate .netdev and .network files, and these interfaces get setup without
any issues. However, when I try to acquire a dhcp lease through the bridge
interface, I am unable to do so. Removing the bridge interface and re-adding
it using brctl (as well as its vlan member) then allows me to gain a lease.
Details are included below. This is on arch linux ARM, systemd 216-r3. As
always, I'm happy to provide any additional information required!
