59 | <para><filename>systemd-hibernate-resume@.service</filename> |
60 | initiates the resume from hibernation. It is instantiated with the | |
61 | device to resume from as the template argument.</para> | |

798d3a52 ZJS |
63 | <para><filename>systemd-hibernate-resume</filename> only supports |
64 | the in-kernel hibernation implementation, known as | |
65 | <ulink url="https://www.kernel.org/doc/Documentation/power/swsusp.txt">swsusp</ulink>. | |
66 | Internally, it works by writing the major:minor of specified | |
67 | device node to <filename>/sys/power/resume</filename>.</para> | |

69 | <para>Failing to initiate a resume is not an error condition. It |
70 | may mean that there was no resume image (e. g. if the system has | |
71 | been simply powered off and not hibernated). In such case, the | |
72 | boot is ordinarily continued.</para> | |
