Description tomashnyk 2022-09-06 19:37:01 UTC

I would like to be able to reboot from GUI using kexec.

kexec is a method to skip BIOS/UEFI during reboot, which can seriously speed up reboot (on my system, it about halves it, BIOS takes about 9 seconds and userspace as much).

It works on systems using systemd-boot pretty much for free.

Hibernate is already an action that fails on a lot of systems (it needs a swap file/partition larger than RAM) and yet is exposed.

Codewise, I think it would need to be implemented from https://invent.kde.org/plasma/plasma-workspace/-/blob/master/libkworkspace/sessionmanagementbackend.cpp

all the way up to https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/kicker/plugin/systementry.cpp
or https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/kicker/plugin/systementry.cpp

(plus a new icon would be handy)

Is such a feature something that would be accepted?

Sounds cool. We could call it "fast boot" or something.

Are you still interested in working on this?

Eventually, yes. Though if somebody implements it before me, I will not be angry :-D.
