I would like to know how the snapshot of the system is taken during hibernation(S2disk) which is then stored in the swap partition.
A typical /etc/suspend.conf shows that the snapshot device to be used is set to /dev/snapshot. Please suggest something to make my understanding better as to how the snaphot image is created and exactly how it is stored at its position which is then loaded into memory on resume(resume device parameter embedded into initramfs).
