From Jaroslav Mracek in private email: "Our solver transforms `kernel- redhat-0.1-42.el9` into name ('kernel-redhat'), epoch (not mentioned but present in metadata -> `0`), version (`0.1`), and release ('42.el9'). The version comparison is not a string comparison - it is more complex and it only uses numbers from the string. Therefore from your example version in RHEL10 is higher than the version in RHEL9. Therefore the upgrade will work."
I'm doing a test to double check right now :smile:
