• -V: Display version information
• -S displays brief device messages
• -A automatically starts all SWAP devices
• -P sets the priority. You can select a number between 0 and 32767. Or add pri = [value] ([value]) in/etc/fstab to 0 ~ 32767), and then you can use swapon-a to start them directly, with priority settings.
