How do I edit a script in /usr/bin on Silverblue?

I’ve a script that is /usr/bin that has a minor error and needs an edit.
It has to be in /usr/bin because it has relative paths

Easy on Fedora Workstation 35, 'cos I just done it to check my diagnosis!

But how do I do same on Silverblue??

Is only way to make a rpm package for it?

Thx
John

You should put it in /var/usr/bin and symlink to it as /usr/bin
