[Nix-dev] (sudo (-H)) nix-collect-garbage

[Florian Friesdorf]

Hi,

can somebody explain me what is going on here? Summary:

- garbage collect as user
- rerun garbage collect as user -> nothing to do
- sudo garbage collect -> more work to do including scary
  'invalidating' actions

Why is root garbage collecting more than user?

Also in a brave moment I waited for the sudo garbage collect to finish
and then tried sudo -H, which gave invalidating messages again.

Currently I don't a have current backup close by, so I lack the courage
to let it continue.

regards
florian
