[Bug 1750681] [NEW] Default kernel command line doesn't work with swapfiles

[Mario Limonciello]

Public bug reported:

Currently hibernating doesn't work in the out of box configuration of
Ubuntu which creates a swapfile by default.

Swapfiles are less discoverable than swap partitions from the
perspective of initramfs-tools and the kernel.

To use them the following kernel command line options are needed:
resume=
resume_offset=

Resume represents the device that will be resumed from that contains the swapfile.
Resume offset represents the location in the disk that the swapfile is located.


Attached is a patch that will populate these two options as necessary

** Affects: grub2 (Ubuntu)
     Importance: Undecided
         Status: New

** Patch added: "patch to populate options by default"
