If both disks have identical bootloaders, I'm not sure there's any way from a running system to check which one you booted from. If you don't mind rebooting it, you could add a different arbitrary kernel argument to the GRUB configuration of each disk's bootloader, reboot the machine, then check /proc/cmdline to see which one shows up. That being said, why does the order matter? So long as you do both correctly before rebooting the machine all should be well. -T.C. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
