Resume partition UUID in /etc/default/grub set to main partition instead of swap when using full disk encryption
When installing Manjaro (KDE flavor, although it shouldn't matter) and using full disk encryption with default partitioning option (root + swap), the 'resume' kernel parameter is set to the luks device for root partition. The hibernation feature (ACPI S4 state) fails with such settings. After manually changing the resume parameter to point to the luks device for swap and regenerating the grub.cfg file, hibernation works without any issue.
