// Main function for the leader process which is responsible for
|
|
// executing all the scripts which make up a Run. Separating this
|
|
// into its own process allows for a cleaner process tree view,
|
|
// where it's obvious which script belongs to which run of which
|
|
// job, and allows this leader process to act as a subreaper for
|
|
// any wayward child processes.
|
|
|
|
// This could have been implemented as a separate process, but
|
|
// instead we just fork & exec /proc/self/exe from the main laminar
|
|
// daemon, and distinguish based on argv[0]. This saves installing
|
|
// another binary and avoids some associated pitfalls.
