systemd-hibernate-resume-generator - Unit generator for resume= kernel parameter


systemd-hibernate-resume-generator is a generator that initiates the procedure to resume the system from hibernation. When resume= kernel command line option or HibernateLocation EFI variable is detected, it enables the systemd-hibernate-resume.service(8) unit, which will instruct the kernel to resume the system from the hibernation image.

systemd-hibernate-resume-generator understands the following kernel command line parameters:


Takes a path to the resume device. Both persistent block device paths like /dev/disk/by-foo/bar and fstab(5)-style specifiers like "FOO=bar" are supported.

Added in version 217.


Takes the page offset of the swap space from the resume device. Defaults to "0".

Added in version 254.


Takes the resume device mount options to use. Defaults rootflags= if not specified.

Added in version 243.


Do not try to resume from hibernation. If this parameter is present, resume= is ignored.

Added in version 240.
