[CentOS] awk global replacement only after keyword

Tell you the truth, I would much rather use sed, but I didn't think
that was doable with it.

I have a slew of txt files that contain a keyword like "service-one"
on many lines. I need to change those, but only the ones that appear
_after_ a known comment.

Thanks!
