What is resume= used for in my grub boot settings?
I've constantly seen the
resume=/dev/foo access in/ boot/grub/menu. lst, which it represents the swap dividing, yet I've never ever doubted its usage.

I was restarting a web server today and also saw a boot message mentioning
Starting manual resume from disk. Seems like some type of hibernate. So just what is resume? I'm attempting to Google it, yet all I'm seeing is resumes/CVs for Linux Admins.
