Tests assume daemon is uid 1

[oneElectron]

---- system::tests::test_get_user_and_group_by_id stdout ----
thread 'system::tests::test_get_user_and_group_by_id' panicked at 'assertion failed: `(left == right)`
  left: `"bin"`,
 right: `"daemon"`', src/system/mod.rs:666:13

This is an error that I get when I run cargo test.
Is there any reason that sudo-rs requires the daemon user be uid 1?

Edit:
Here is the link to the relavent test:

System

Here is the top of my /etc/passwd:

root:x:0:0::/root:/usr/bin/fish
bin:x:1:1::/:/usr/bin/nologin
daemon:x:2:2::/:/usr/bin/nologin

Here is the /etc/group greped for daemon:

adm:x:999:daemon
bin:x:1:daemon
daemon:x:2:bin

I am currently running a 13 inch M1 Macbook pro running asahi linux (Arch linux ARM).

Oh, that's because those tests are run on CI only where uid 1 will be daemon. We could disable those for local runs using the env macro or something similar.

[oneElectron]

Ok the env macro sounds nice. I would like to contribute to sudo-rs so maybe I could write fix this myself.
I like to env variable idea but the other option would be to add an #[ignore = "ci"] to the test.

Go ahead, if you want to discuss your solution before shooting it in as a PR feel free to do that here.

[oneElectron]

Currently my preferred solution is to mark any tests that might fail on a local system with #[ignore = "ci"]. In .github/workflows/ci.yaml there must be a -- --include-ignored to any runs of the tests like so:
https://github.com/oneElectron/sudo-rs/blob/4883a282c57f168bc024c7e5c25d9d4f1cc681af/.github/workflows/ci.yaml#L218-L222
and so:
https://github.com/oneElectron/sudo-rs/blob/4883a282c57f168bc024c7e5c25d9d4f1cc681af/.github/workflows/ci.yaml#L258-L262.

Here's an example run of cargo test:
