Thanks for the reply. It indeed works. But there is one thing I find counter-intuitive: s6-test expects to see an escaped ! while export doesn't. For example this exits 1:

#!/usr/bin/execlineb -P
export \\\! 0
s6-test -v \\\!

quoting is different in execline, i think there was
more written in some documentation for the specifics, but i think it
needs to both escape the ! and the \ , so it's three levels of  >
as a bonus, that also works in normal shell (no quoting in both places)
