Workarounds currently in > use can be seen in our mutter package definition (it's a bit convoluted, > having to fork a process in which we set the child reaping property and > invoke the test suite via tini, acting as a fake PID 1). The Guile process running the build script (with the build phases) runs as PID 1. So how about doing one of these: 1. Add a final phase that does (waitpid WAIT_ANY). 2. Add a SIGCHLD handler that calls =E2=80=98waitpid=E2=80=99. I suspect the former is enough. Eventually, we should do one of these in gnu-build-system.scm, as in: https://issues.guix.gnu.org/30948#2 WDYT? Ludo=E2=80=99.
