==================

[codefromthecrypt]

this will fail until the e2e tests in the debug directory are moved to test/e2e and backfilled with unit tests

there are also some signal tests that fail, but should go away with #172

[codefromthecrypt]

go test -race ./pkg/util/exec also fails

[codefromthecrypt]

still an issue
