If you want a suspend to disk solution that:
- requires little setup
- looks pretty
- is very fast to suspend and resume
- leaves the machine in responsive state
- can suspend to swap partitions, swap and regular files or combo thereof
Suspend2 really is "last resort". Rafael says that uswsusp will get there (minus the "little setup" bit), so that's good news. However, at the moment, Suspend2 is the *only* solution that provides all of the above. It's a shame Suspend2 isn't in the mainline, especially given the fact that it doesn't remove swsusp nor uswsusp and can be compiled in/out easily.
> Nigel has not been particularly effective in his dealings with the rest of the kernel development community
Nigel has been working hard to meet the demands of other developers. /sys support is already in. The code of Suspend2 shares more of swsusp code these days etc. And, let's not forget, Nigel is still supporting all of the Suspend2 users - he sure isn't sitting idle.
To me, it does seem that some other developers repeatedly come up with requests that are based on misconceptions (e.g. that Suspend2 does user interface inside the kernel or that cryto/compression cannot be easily removed from the rest of the code). Sure, there are still some real technical complaints before Suspend2 can be merged, but I'm sure Nigel and others will eventually address those.
