radvd only gives out the prefix of the "first" IPv6 address of an interface
Plus Target Version:
Situation: When multiple prefixes are available on an interface (like a PD'd GUA and a locally defined ULA), only the first one gets sent out through the RA.
Now, I could live with this if it was consistently the PD'd IP that got sent out, and I could add my own ULA as additional prefix in the GUI if I wanted to (since I might want to deal out the ULA through DHCPv6 instead of SLAAC), but then the RA would have to consistently be able to send out the PD'd prefix. Currently it is unnpredictable, or predictably wrong.
