I don't have a way to verify the change. If anyone is able please do.

@open-telemetry/specs-approvers can anyone review/verify this PR? If no-one knows how I am going to close it as "stale".

[hdost]

well that's unfortunate 😢

@tigrannajaryan is the other PR proof enough for you?
If so I'll update it.

@hdost

Please note that I used -z, lowercase, not -Z, uppercase, for open-telemetry/opentelemetry-cpp#2455. Not sure which one you need to generate proto files.

I am not sure in this context it needs to be shared but I can also make that change.

@marcalff @ThomsonTan can you please review this PR? If we get both your approvals we should be able to move forward.

Verified that code generation fails without the fix for SELINUX systems.

[malff@malff-desktop opentelemetry-proto]$ make
rm -rf ./gen/cpp
mkdir -p ./gen/cpp
docker run --rm -u 1000 -v/data/malff/CODE/MY_GITHUB/opentelemetry-proto:/data/malff/CODE/MY_GITHUB/opentelemetry-proto -w/data/malff/CODE/MY_GITHUB/opentelemetry-proto otel/build-protobuf:0.9.0 --proto_path=/data/malff/CODE/MY_GITHUB/opentelemetry-proto --cpp_out=./gen/cpp opentelemetry/proto/resource/v1/resource.proto
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
opentelemetry/proto/resource/v1/resource.proto: File does not reside within any path specified using --proto_path (or -I).  You must specify a --proto_path which encompasses this file.  Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).
make: *** [Makefile:56: gen-cpp] Error 1

Verified that code generation works with the fix for SELINUX systems.

Approved, thanks for the fix.

@open-telemetry/specs-approvers please take a look. I think this is good to merge and verified to work by @marcalff.
