I wonder if fuse-overlayfs <https://github.com/containers/fuse-overlayfs>
on top of osxfuse <https://ports.macports.org/port/osxfuse/> would allow
apparent modification of /usr/bin without touching the underlying sealed
FS. I see that Homebrew has a formula for it
<https://formulae.brew.sh/formula/fuse-overlayfs>, though there doesn't
seem to be a port for it in MacPorts.
