+description = """The qemu-guest-agent's shutdown calls `/sbin/shutdown` with the apropriate flags to shut down a posix system. On Alpine Linux, which is based on busybox, there is no `/sbin/shutdown`, instead there are `/sbin/poweroff`, `/sbin/halt` and `/sbin/reboot`. We have used a downstream patch for years that will exec those as a fallback in case execing `/sbin/shutdown` fails.
+
+With qemu 9.2 this patch no longer applies and it is probably time to solve this properly in upstream qemu.
+
+The question is how?
+
+Some options:
+
+- Set the powerdown, halt and reboot commands via build time configure option
+- Add a fallback if the `execlp` fails (similar to what downstream Alpine's patch does now). We could for example give `ga_run_command` a `const char **argv[]`, and try `execvp` all of them before erroring out.
+- Test the existence of `/sbin/shutdown` before calling `ga_run_command`.
+- Do nothing. Let downstream Alpine Linux handle it."""
