Hi @galal-hussein @cwayne18 & @briandowns :
After merging this PR, we discovered that when setting up k3s on SUSE Linux Enterprise Micro, it encountered a permission-related error because it attempted to execute transactional-update without using sudo. I am unsure whether this behavior is expected or not.
