๐Ÿ’ค SYSTEMD-....SERVICE(8) โ€” the systemd-hibernate-resume@.service page, section 8 bestie

okay so welcome to the manual page for systemd-hibernate-resume@.service and systemd-hibernate-resume ๐Ÿ’– this is the girl who wakes your computer back up after a nap. she's important. let's get into it.


โœจ NAME โœจ

systemd-hibernate-resume@.service, systemd-hibernate-resume โ€” resume from hibernation ๐Ÿฆ‹

like. that's the whole job. waking up from the big sleep.


๐ŸŒธ SYNOPSIS ๐ŸŒธ

systemd-hibernate-resume@.service
/lib/systemd/systemd-hibernate-resume

๐Ÿ’… DESCRIPTION ๐Ÿ’…

systemd-hibernate-resume@.service initiates the resume from hibernation. it gets instantiated with the device to resume from as the template argument โ€” so like, you hand it a device and it's like "say less, I got you" ๐Ÿซถ

systemd-hibernate-resume only supports the in-kernel hibernation implementation, see Swap suspend down in the notes ๐Ÿ‘€. internally, the way it works is it writes the major:minor of the specified device node to /sys/power/resume. that's it. that's the whole trick. iconic behavior honestly.

ngl, failing to initiate a resume is not an error condition. it may mean that there was no resume image โ€” like if the system has been simply powered off and not hibernated. in such case, the boot is ordinarily continued. so don't panic, bestie, it's giving "nothing to see here" ๐Ÿ’€
