2023-09-12[#201] Deduce profile directory during activationRoman Melnikov1-13/+97
Problem: Since https://github.com/NixOS/nix/pull/5226 nix profiles for users are stored in 'XDG_STATE_HOME' or 'HOME' directory. However, 'deploy-rs' still expects profiles to be present in '/nix/var/nix/profiles/per-user'. As a result, an attempt to deploy a profile with newer nix may fail with an error about non-existing files. Solution: Instead of deducing the profile path prior to ssh'ing and actual activation, deduce the path to the profile during as a part of 'activate-rs' invocation. Now if the profile path is not specified explicitly as an attribute in profile within the deploy flake, the path to the profile is determined based on the user to which the profile belongs and on the values of 'XDG_STATE_HOME' and 'HOME' variables. Additionally, if the old profile directory (in '/nix/var/nix/profiles/per-user') for a given user already exists, it is used instead for the sake of backward compatibility.
2023-04-20[Chore] Handle 'temp_path' as an actual 'Path' instead of 'String'Roman Melnikov1-11/+16
Problem: 'temp_path' and 'lock_path' are handled as 'String'. This can be a problem when the 'temp_path' directory is a symlink on the target system, e.g. this is the case with the default '/tmp' and macOS, where this directory is actually a symlink to '/private/tmp'. Solution: Handle 'temp_path' and 'lock_path' as actual Paths. Also, canonicalize 'temp_path' to avoid canary file path mismatches when checking filesystem events. As a side effect, also update the 'notify' dependency to the latest stable version.
2022-10-09Add new activation strategy `boot` as equivalent to `nixos-rebuild boot`Maximilian Bosch1-1/+8
This can be useful when e.g. deploying a kernel update to a target host. You usually plan a reboot (or kexec) after that to activate the new kernel. However you don't want to wait for services to be restarted first since these will be "restarted" anyways on the reboot. In cases like GitLab or the Atlassian stack this actually makes a difference. This patch changes the following things: * If `--boot` is provided, `nix-env -p profile-to-activate --set` is called for each deployed profile to make sure that it is activated automatically after a reboot. * However, the actual activation (e.g. `switch-to-configuration switch`) is skipped. Instead: * For NixOS, `switch-to-configuration boot` is called to set the new profile as default in the bootloader. * For everything else, nothing else is done. The profile is already the new default (and thus picked up on the next boot).
