Can we at least use posix_spawn rather than system? The asprintf+system
combo may in practice be safe, especially given the nature of this
tool, but I don=E2=80=99t think it=E2=80=99s a great idea to be writing =
system-using
code in 2024 when it=E2=80=99s easy to avoid. That way nobody needs to =
stop and
think carefully about whether the code is safe, because it is by
construction.
