# What scripts/coverage.sh runs the Rust tests in, to see which lines they reach (#390): the
# toolchain, LLVM's coverage tools and cargo-llvm-cov. No source: coverage.sh mounts the tree.
# Built and pushed like the services, by scripts/build-image.sh coverage, under its caps.
#
# Ubuntu 24.04, as code-server is (#394): `coverage.sh api` builds an instrumented ipx and
# ipx-directory here, under the cap, and the browser suite runs them in code-server, which a
# binary linked against Debian trixie's newer glibc (2.41 to Ubuntu's 2.39) would not start in.
# The same Rust as the tests are built with elsewhere: a newer one would rebuild everything with
# its own flags for nothing.
