apfs-fuse: Let mount find apfs-fuse #84997

merged 1 commit into from Oct 9, 2020

@jcpetruzza jcpetruzza commented Apr 11, 2020

Motivation for this change

On other distros, using fuse.apfs-fuse as mount type should work since mount.fuse will then call apfs-fuse, but on nixos the PATH exposed to mount.fuse is restricted. The symlink makes this work directly, by having mount find mount.fuse.apfs-fuse in its PATH.

In particular, this let's us use fuse.apfs-fuse as fsType when defining mounts in nixos. The
current alternative is to specify: fuse./run/current-system/sw/bin/apfs-fuse
as fsType.

I'm following #14302 for this fix.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits
We add a symlink `mount.fuse.apfs-fuse ~~> apfs-fuse`, so that we can specify
`fuse.apfs-fuse` as `fsType` in `nixos` and have the device mounted. The
current alternative is to specify: `fuse./run/current-system/sw/bin/apfs-fuse`
as `fsType`.

On other distros, using `fuse.apfs-fuse` should work since `mount.fuse`
will just runs `apfs-fuse`, but on nixos the `PATH` of `mount.fuse` is
restricted. The symlink makes it work directly, without having
`mount.fuse` doing the dispatch.

@stale stale bot commented Oct 9, 2020

Hello, I'm a bot and I thank you in the name of the community for your contributions.

Nixpkgs is a busy repository, and unfortunately sometimes PRs get left behind for too long. Nevertheless, we'd like to help committers reach the PRs that are still important. This PR has had no activity for 180 days, and so I marked it as stale, but you can rest assured it will never be closed by a non-human.

If this is still important to you and you'd like to remove the stale label, we ask that you leave a comment. Your comment can be as simple as "still important to me". But there's a bit more you can do:

If you received an approval by an unprivileged maintainer and you are just waiting for a merge, you can @ mention someone with merge permissions and ask them to help. You might be able to find someone relevant by using Git blame on the relevant files, or via GitHub's web interface. You can see if someone's a member of the nixpkgs-committers team, by hovering with the mouse over their username on the web interface, or by searching them directly on the list.

If your PR wasn't reviewed at all, it might help to find someone who's perhaps a user of the package or module you are changing, or alternatively, ask once more for a review by the maintainer of the package/module this is about. If you don't know any, you can use Git blame on the relevant files, or GitHub's web interface to find someone who touched the relevant files in the past.

If your PR has had reviews and nevertheless got stale, make sure you've responded to all of the reviewer's requests / questions. Usually when PR authors show responsibility and dedication, reviewers (privileged or not) show dedication as well. If you've pushed a change, it's possible the reviewer wasn't notified about your push via email, so you can always officially request them for a review, or just @ mention them and say you've addressed their comments.

Lastly, you can always ask for help at our Discourse Forum, or more specifically, at this thread or at #nixos' IRC channel.
