Reading more, it seems the answer is yes:
https://skarnet.org/software/s6/notifywhenup.html
So, s6 has a built-in mechanism where, when the supervised process is
available ("ready" in the s6 nomenclature), it writes a line to a file
descriptor and closes it.
If the supervised process does not support the file descriptor
notification mechanism, a workaround is the s6-notifyoncheck program:
https://skarnet.org/software/s6/s6-notifyoncheck.html
This all looks promising! Thank you, Laurent, for writing and
maintaining s6!
Lewis
