Comment:

 There is this issue with cargo in the jenkins builds:
 https://jenkins.torproject.org/job/tor-ci-linux-master-
 rust/ARCHITECTURE=i386,SUITE=sid/24/console where it spits out `error:
 error: attempting to make an HTTP request, but --frozen was specified`.

 This is due to part of the cargo source code,
 `init_git_transports(config);` in the `execute` function of
 `cargo.git/src/bin/cargo.rs`, trying to obtain a copy of the registry (the
 git repo that tells you about which crates are published). Alex Crichton
 realised that it's due to building in a directory which doesn't have a
 `cargo` subdirectory (nor do any of its parents), which is due to us doing
 jenkins builds out-of-tree. The solution, or at least a workaround, is to
 do `cp -aR build-tree/src/rust/.cargo ~/` after running
 `../tor/configure`.

 Here is a [https://github.com/isislovecruft/tor-jenkins-
 tools/commit/f8af924a75902f261874fe1670a56d63cef942eb patch].
