Do you use the ability to change the text being substituted here downstream ? If so, heads-up that I'm working on a conversion of this texi file to rst. I'll put in a similar rst substitution-reference, which will look like this: .. |qemu_system| replace:: qemu-system-x86_64 but you'll need to update your downstream processes if you're changing the value in the texi currently. thanks -- PMM
