As I wrote

At least this is where I do it and it works for me.
My use of "global" was probably not so lucky, I did not mean bitbake
configuration. I just meant that it is done in the image recipe and not
in the node recipe.
You can always use "bitbake -e" to check variable and recipe function
definitions if you are wondering what is really going on. I often
understand problems when looking at the listing produced by this
command. In your case "bitbake -e core-image-full-cmdline"
There are also other functions in the value of ROOTFS_POSTPROCESS_COMMAND so as

The final value of ROOTFS_POSTPROCESS_COMMAND as shown by "bitbake -e"
should be list of function names separated by semicolons.
My previous link was broken, hopefully this time it survives intact...

That has never happened to me and I use underscores in my function
names. But I could imagine that it's possible in some case. I would
strongly expect to see such issue in the output of "bitbake -e", too.
