That would be bad, as PID1 is the one reaping dead child
processes. Thus daemons should have it as their parent, and
doubly-forked processes already do, just as any orphaned
process will eventually end up having a PPID of 1.

Unless PID2 is a dedicated process supervisor that monitors
its children and does the bookkeeping, but I would not expect
that from the shell script in the example above.
