Got a bit further on Rust 1.59, but broken on `Arc::new_cyclic`. Looks like we need [Rust 1.60](https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1600-2022-04-07) for that; bumping again.

After locally patching guix to bump the rust version to 1.60, it mostly works: ``` 1% tests passed, 12 tests failed out of 131 Label Time Summary: linux = 69.08...

Some of the failures were due to not having `lscpu` in my guix environment, which shadow needs when pinning is enabled, and is part of the `util-linux`. ``` $ ./pre-inst-env...

We might be able to address the absolute-path problem by using guix's container support. That'd also ensure that we're not accidentally depending on other things in the host system. It...

After discussion this is semi-shelved, but I might poke some more on my own time because I'm interested in guix. The rust-bump patch got merged into guix's staging. After that,...

Another option might be to do away with the explicit `host_defaults` field and use yaml anchors. The `

@robgjansen should this be closed? (Or maybe not; I never looked closely at the new cleanup implementation)

`test_time.rs` tests `clock_gettime`. It could probably be extended pretty easily to test the other time APIs as well.
