systemd systemd-hibernate-resume-generator 8 systemd-hibernate-resume-generator Unit generator for resume= kernel parameter /usr/lib/systemd/system-generators/systemd-hibernate-resume-generator systemd-hibernate-resume-generator is a generator that initiates the procedure to resume the system from hibernation. It creates the systemd-hibernate-resume.service8 unit according to the value of resume= parameter specified on the kernel command line, or the value of EFI variable HibernateLocation, which will instruct the kernel to resume the system from the hibernation image on that device. systemd-hibernate-resume-generator understands the following kernel command line parameters: resume= Takes a path to the resume device. Both persistent block device paths like /dev/disk/by-foo/bar and fstab5-style specifiers like FOO=bar are supported. resume_offset= Takes the page offset of the swap space from the resume device. Defaults to 0. resumeflags= Takes the resume device mount options to use. Defaults rootflags= if not specified. noresume Do not try to resume from hibernation. If this parameter is present, resume= is ignored. systemd1, systemd-hibernate-resume.service8, kernel-command-line7
