SYSTEMD-HIBERNATE-RESUME-GENERATOR(8)

💤 SYSTEMD-HIBERNATE-RESUME-GENERATOR 💤

okay so bestie, welcome to systemd-hibernate-resume-generator(8) — the little generator with a very long name and one job, and honestly? it slays at that job. 🫶

✨ SYNOPSIS ✨

/usr/lib/systemd/system-generators/systemd-hibernate-resume-generator

that's it. that's the whole vibe. no flags, no args, just a path. 💅

---

🌸 DESCRIPTION 🌸

so systemd-hibernate-resume-generator is a generator (iykyk, one of those little boot-time helpers) and its whole thing is kicking off the procedure to resume your system from hibernation. like, waking your computer back up from its lil nap. 😴➡️😳

the way it works: the moment it spots either the resume= kernel command line option or the HibernateLocation EFI variable, it's like "not me finding a hibernation image" and it enables the systemd-hibernate-resume.service(8) unit. and that unit? that's the one that tells the kernel to actually resume the system from the hibernation image. teamwork, fr fr. 🤝✨

🎀 KERNEL COMMAND LINE 🎀

here's the tea — systemd-hibernate-resume-generator understands these kernel command line parameters:

• resume= — takes a path to the resume device. and it's flexible bestie: both persistent block device paths like /dev/disk/by-foo/bar and fstab(5)-style specifiers like "FOO=bar" are supported. iconic behavior. 👑

added in version 217.

• resume_offset= — takes the page offset of the swap space from the resume device. defaults to "0" if you don't say anything. no thoughts, just offset. 🔢

added in version 254.

• resumeflags= — takes the resume device mount options to use. defaults to rootflags= if it's not specified. cute lil fallback. 🍓

added in version 243.

• noresume — do not try to resume from hibernation. if this parameter is present, resume= gets completely ignored. like, ghosted. 💀

added in version 240.

heads up bestie: noresume is the "actually no thanks" button, and it overrides resume= entirely, so don't set both and then act surprised. 🙈
