In FreeBSD GH workflow (defined in .github/workflows/freebsd.yml), GH actions are used to cache the Rust build artefacts:

• Swatinem/rust-cache@v2
• mozilla-actions/[email protected]

Theses actions are useless because the Rust build artefacts are not copied back from FreeBSD guest to Ubuntu GH runner after build:

• FreeBSD workflow uses vmactions/freebsd-vm: runs a FreeBSD guest (VM) in a GH Ubuntu runner (host)
• Files are synced between guest and host via rsync sync: rsync
• At the end of job, the files are not copied back from FreeBSD guest to Ubuntu host: copyback: false.

Proposal to remove the 2 actions in FreeBSD workflow or to fix sync of files between guest/host after build to use cache.
