okay so I now understand what was going on
I have a very special setup on this NixOS machine, with full disk encryption and an SSH daemon in initramfs (stage 1 boot), with a disk encryption password prompt.
And, apparently by default that configuration is just kept in stage 2 boot.
You need to specifically add an option to not keep that configuration in stage 2 boot.
Also, apparently the ip=dhcp kernel parameter I'm using is kinda weird, and it's not documented what it does with IPv6 but it looks like it just assigns an EUI-64 address, which works for me I guess.
edit: the option that's supposed to flush the stage 1 network configuration doesn't work so fuck it I'm just gonna roll with this
