I should perhaps add that I've been using the Yocto update-rc.d bbclass
very happily.

I can patch out the autotools hooks in Makefile.am and my recipe will
work fine.

What I'm not understanding is if there's a standardised way to write the
autotools configuration
that would eliminate the need for Yocto update-rc.d
