Docker Tab, top right, advanced view
My problem is that sure I could've set the patch to work with Unraid 6.0+ (or more realistically 6.8+) But, if things went sideways and/or it didn't actually work on those versions then I'd have to actually go and install / set up that particular version and adjust accordingly. Basically though, you want to add in the applicable command to the "go" script (/config/go on the flash drive) to handle the adjustments if/when you reboot.
But, you're better off updating as any script that you have adjusting base OS files might actually cause problems if / when you update to an OS version that already has the fixes in place. This is the reasoning behind the script and the codicil of "Highly advised NOT to run a script..."
Devil's advocate in me though has to question the rationale behind the OS is a set it and forget it, but you're updating the containers because of new features, security enhancements etc...
