If you’re running ubuntu or a debian based distribution and you want to speed up your shutdown/reboot process then I have built a little script which can safely remove services, create a backup of those services and also remove services which may not be useful on your system (for instance, usplash).
In short, it is a script which theoretically will speed up the ubuntu shutdown/reboot process.. although I havn’t done any benchmarking with it so I dont really know.
I’m not really working on it at the moment although I might go back to it in the future. If you wanna use it or develop it further than go ahead. It’d be cool for someone to create a GUI and use it as a backend similar to BUM (Boot Up Manager). If you have any fixes/changes/suggestions then I’ll probably implement them if they are any good.
