%description
sccache is a ccache-like compiler cache: a compiler wrapper that caches
compilation results in local or remote storage. This build enables the Redis
and GitHub Actions cache backends and the distributed-compilation client.
(Fedora's sccache omits the Redis backend.)

%package -n sccache-dist
Summary:        Distributed compilation scheduler and build server for sccache
# The server subcommand shells out to bwrap (>= 0.3.0) to sandbox jobs; the
# scheduler does not, so this is a weak dep.
Recommends:     bubblewrap

%description -n sccache-dist
sccache-dist is the server side of sccache's distributed compilation: a
scheduler that parcels compile requests out to build servers, and a build
server that runs them in an overlayfs + bubblewrap sandbox. Ships hardened
systemd units and a sccache system user.

# -n drops the default `all` set (webdav/memcached/s3/gcs/azure/oss/cos we don't
