with the size of drives today is it really that bad to require a seperate

Yes. You want uswsusp to work in situations where swsusp worked.

I also don't like the idea of storing this in the swap partition for a
couple of reasons.

1. on many modern linux systems the swap partition is not large enough.

for example, on my boxes with 16G or ram I only allocate 2G of swap

WTF? So allocate larger swap partition. You just told me disks are big

swap partitions are limited to 2G (or at least they were a couple of months ago when I last checked). I also don't want to run the risk of having a box try to _use_ 16G worth of swap. I'd rather have the box hit OOM first.

2. it's too easy for other things to stomp on your swap partition.

for example: booting from a live CD that finds and uses swap

That's a feature. If you are booting from live CD, you _want_ to erase
any hibernation image.


it's been stated that doing a std and booting another OS (including windows) is a valid and common useage. saying that if you boot another OS you trash your suspended image doesn't sound reasonable.
