This new feature bypasses checking if a swap partition is mounted or if there is enough swap space available for hibernation to succeed. This can be useful when a system with a Solid State Disk (SSD) has no normal swap partition or file configured, and a custom systemd unit is used to mount a swap file just before hibernating and unmount it just after resuming.

We don't do S-o-b in systemd btw, see CODING_STYLE. |

This patch adds a new debug feature that bypasses checking if a swap partition is mounted or if there is enough swap space available for hibernation to succeed.
This can be useful when a system with a Solid State Disk (SSD) has no normal swap partition or file configured, and a custom systemd unit is used to mount a swap file just before hibernating and unmount it just after resuming.
This is a follow-up to #3006.
I'm personally using this feature along with this unit:
