oss-fuzz Centipede is bloating our image sizes.

It reinstalls clang? and adds 1.7GB to our image size, which slows down every CFL/CIFuzz user.

I think it reinstalls using apt and via tar.gz and does some stuff to /usr/bin/bazel that wastes 50 MB. Might be worth making a multistage build if this won't install cleanly.

Shall we close this as it has been fixed?

I'm not sure it has. It's worth looking at how much space the centipede layer is taking and if it should be reduced further.

This is still adding a few hundred MB of into /usr increasing our image size by about 25%

This was fixed by https://github.com/google/oss-fuzz/issues/8468 Now the centipede is a more reasonable 11 MB :tada:
