Job linux:stable fails with compile error in step make tests

Problem

As the moment of writing, the job linux:stable fails because of a compiler error on component file.

For example, this happens under this PR and this PR. They both got the same error.

This jobs seems to fail for this reason.

error: could not rename component file from '/root/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/share/doc/cargo' to '/root/.rustup/tmp/l6w0u6l2ukry_npa_dir/bk': Invalid cross-device link (os error 18)
   Compiling types-rs v0.1.0 (/builds/bool_purist/ion/members/types-rs)
error: could not compile `thiserror`

See job output

Cause of the Problem in my view.

Some research seems to suggest that a component file got corrupted. See this github issue. It recommended to reinstall the toolchain. Since the job is using the base image redoxos/redoxer on docker hub, the installation of the rust toolchain in the Dockerfile of the repository might have gone wrong.
