SYSTEMD-HIBERNATE-RESUME.SERVICE(8)           systemd-hibernate-resume.service

NAME
       systemd-hibernate-resume.service, systemd-hibernate-resume - Resume
       from hibernation

SYNOPSIS
       systemd-hibernate-resume.service

       /usr/lib/systemd/systemd-hibernate-resume

DESCRIPTION
       systemd-hibernate-resume.service initiates the resume from hibernation.

       systemd-hibernate-resume only supports the in-kernel hibernation
       implementation, see Swap suspend[1]. Internally, it works by writing
       the major:minor of selected device node to /sys/power/resume, along
       with the offset in memory pages (/sys/power/resume_offset) if
       supported.

       Failing to initiate a resume is not an error condition. It may mean
       that there was no resume image (e. g. if the system has been simply
       powered off and not hibernated). In such cases, the boot is ordinarily
       continued.
