Very good.

Continuing that.

ISTR OpenSUSE having something like it.  I'm using the "uswsusp" package on 
Debian.  "uswsusp" = [U]serspace [S]oft[W]are [SUSP]end.

While I can understand that, I don't agree with it.

On slower laptop hard-drives writing pages to disk can take a few minutes to 
finish.  That process isn't interruptable, so I can imagine use cases where 
the user would actually prefer just using suspend to RAM.  Laptop users with 
solid-state disks might also have issues with the additional wear, maybe?

Instead, I think it might go like this:
s2ram -> Fast Sleep
s2both -> Safe Sleep
s2disk -> Hibernate

Can do.  I'll file a bug / feature request first, but I should be able to add 
"s2both" though the chain easily enough.  I'm not at all familiar with their 
source or configuration, but it should be limited to C/C++, shell, XML, and 
some plain-text formats, right?

Please CC me on replies; I am not subscribed to kde-devel or kde-hardware-
devel.
