[Nix-dev] Notes and ideas about the Nix-UI proposal

[zimbatm]

I keep seeing this transaction argument but what is the use-case for it ?

For complex scenarios I think it would be best to have a user-equivalent of
the /etc/nixos/configuration.nix file and a `nix switch` command to apply
the changes in a transactional manner. Then `nix install` and friends might
be implemented in terms of amending the user's configuration.nix or related
file and then run `nix switch`. That way it's easy to synchronize the
profile between computers. `nix install` might even gain a `--no-switch`
flag to just manipulate that list.
