A rummage around the interweb will find the devuan.xpm file you need,
then a simple edit and job done. I did it on my iMac. Details to follow
when I've finished my bottle of wine.

Also, 'su' is just wrong, don't use it, always use sudo, and if you can
find a decent .deb of OpenBSD 'doas' ported to linux use that, it is
even better!
