SYSTEMD-....SERVICE(8) systemd-hibernate-resume.service SYSTEMD-....SERVICE(8)
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 specified 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.
