OK, I see there are features to make life easier when I decide to use suspend. But it looks like that using suspend is the goal and dealing with the constraints is a lot of work and I'm still far from being convinced that it would provide me advantage. > > - I would certainly not keep open documents that are on crypted FS > > while I travel.

Unless I'm mistaken, I have to type the passphrase twice then : - once at suspend - once at resume which is once more per "boot" than what I'm doing on loop-aes. > You could also close the document and not the app. Or both and just get > the benefit of having the app in page cache post-resume.

I really think that this feature is clearly not for me but it's more featureful than I initially thought, and I could encourage some people to give it a try.
