I would prefer that we not check in Cargo.lock in Git.  Part of the
reason is that it changes across versions and so building with a
different version of the toolchain can update the file.

In addition, as I mentioned downthread, because our intention is to
support the Debian stable toolchain for a year after the new stable
release, unless we are exceptionally careful about dependencies, we may
end up with a case where distros need to use older dependencies patched
for security but other users may want to update the versions to newer
dependencies with security fixes but that do not work on our pinned Rust
version.  We can't possibly satisfy both sets of people if we pin
dependencies in Cargo.lock, so we probably want to avoid checking it in
and ignore it instead.

Yup.  

The comment in first few lines of the file says it very well ;-)
Thanks for flagging it.
