Can you hibernate to a swap *file*? I thought it had to be a partition.
How would you set up the resume line for that?
It has to be a partition. A file can be on any kind of filesystem, so
how would the resume function know what to do?
From systemd-hibernate-resume(8):
systemd-hibernate-resume@.service initiates the resume from hibernation. It is
instantiated with the device to resume from as the template argument.
systemd-hibernate-resume only supports the in-kernel hibernation
implementation, known as swsusp[1]. Internally, it works by writing the
major:minor of specified device node to /sys/power/resume.
That's why I'm confused about the original question. He made a swap
file for hibernating and it's not working because of an selinux issue.
But even if that is resolved, it's still not going to work.
