Yes - you make a good point about the rules for the DUID. So I'm back
to using different NM profiles or a script that sets a different
static IPv6 address depending on the VLAN RA,

In order to get different IPv6 address from SLAAC, you may
try `ipv6.ip6-privacy ` (RFC 4941).

But you still need to solve the IPv6 prefix problem. Each VLAN should
has its own DHCP pool and RA prefix.

My situation is with laptops in a large organisation with a
central DHCP service. The DUID is static and so the laptop gets
the same IPv6 address even when it's moved to a different VLAN
with a different prefix. When  I realise the IPv6 address is
not appropriate I delete the lease file and then it all works
until the laptop moves VLANs again.
