# We keep a rust-toolchain file checked into the repository such that in the
# rare event that we need to do an A/B-test across toolchains, cargo will
# download the toolchains of the A and B revisions on the fly (if they do not
# match the toolchain installed in the environment in which the test is
# executed). This is needed for example if a toolchain upgrade introduces a new
# syscall into our seccomp filters. Then, since our PR CI contains A/B-tests,
# we will compile a version of Firecracker that does not have this syscall
# allowlisted using a toolchain that requires it, causing the A/B-test to
# always fail.
