Trouble with the installer after migrating to a new Mac via MacOS's Migration Assistant about nix-installer

Yes. I really appreciated the (not shown) instructions the installer provided that I should edit /etc/fstab, but it's a bit unfortunate that the installer didn't quite know how to function afterwards.

Thanks for making the installer, by the way, I imagine things would be far more painful without it.

Not sure if it'll apply to this installer, but there's also a known issue with ~official installs not functioning correctly after migration due to some small difference between freshly-created nixbld group/users and what you end up with after running migration assistant.

Good news: running the installer again seems to have worked. This is after whatever cleanup the previous run performed, as seen in the transcript.

I'm so glad it worked out! It's unfortunate you met this. I believe it is related to the fact that we use APFS provided UUIDs in places like the fstab which change when a migration happens...
