I think the closet you can come is going to runlevel 1 and then back to run level 3 or 5. init 1 then init 5

This will not reload the kernel. Yet it might reload a few modules, but likely not, as so far that I know, module unloading is not forced.

You are right, but it's as close as you can get. Maybe dropping down to "single" would be better than 1. -- use Perl; #powerful programmable prestidigitation

Under z/VM it is possible (IBM mainframes). You do have to recompile the kernel to enable the code, but then you can save the system, at a predetermined state, to disk. When you have to reboot a Penguin farm, this is quite a time savings.

That reminds me of what laptops do: "suspend to disk". I wonder why that can't be applied to desktops, it certainly would be useful. -- use Perl; #powerful programmable prestidigitation
