Tests seem to pass now. @roberth do you want to squash things a bit, so we can backport patches? |

Please undraft, if you need a new review. |

Thanks for the reminder. I was still adding a regression test, 73871f2 when I was interrupted (rudely ;) ) by the maintainer meeting today. |

@mergify rebase |
Tested with
nix run nix/2.3-maintenance#nix-store -- --add some_symlink
nix run nix/2.3-maintenance#nix-store -- --add-fixed sha256 --recursive some_symlink
…makeParentCanonical I'd messed up a rebase in my previous iteration, causing `weakly_canonical` to reappear, but not trigger a test failure. These two functions behave similarly when the argument is a path that points to a broken symlink. `weakly_canonical` would not resolve it because the target doesn't exist, and `makeParentCanonical` would not resolve it, because it never resolves the final path element. This new test case now also tests a valid symlink, "differentiating" the two.

This is still an issue in 2.24. Any plans to tag a maintenance release soon? |

Motivation
PosixSourceAccessordoes not operate on non-canonical paths, yet manycreateAtRootcalls did not canonicalize their inputs.See commit messages and comments for details.
Probably more
createAtRootcalls need this kind of treatment, but that's not a prerequisite for reviewing what's probably the bulk of the change, and the ideas behind it.Context
