comment Permanently assigning IP address for an embedded device
Okay, my new approach is to, on boot, obtain an link-local address one time using the implementation at zeroconf.org/AVH-IPv4LL.c. I then do an ifconfig add eth0:0 user_configurable_ip_address to add an alias. This is not so robust if I move my device to another network while powered, but it's powered by its Ethernet cable, so it should almost always follow the link-local address acquisition rules. (reboots upon disconnect)

A collision only happens if communication is attempted with the duplicate address, right? Nothing will attempt to use this address except for the ARP queries from link-local address negotiation, which is meant to happen. What's the practical effect of this collision?

comment Embedded device configured with bad IP address, can I still connect?
This is my main problem. I do not know what address and mask the embedded device's interface is actually using, if any. What steps can I take to diagnose this, and can I use Zeroconf to help?
