NAK. Of course I have the united states army in front of my notebook
to protect my pronsite passwds. But see, the army makes my notebook 
an interesting target for data-thiefs, right? So I want encrypted swap
as an additional feature.
Okay stop kidding, of course crypted swap is no allround solution, but 
a step to harden your security issues. I don't want to make you using
it, but I can think of people who would want to including myself.

ACK.

Thank you, this was what I meant when I wrote of some BSD :).

Okay, so I got some ideas how to implement, the kernel-related
thing with an automatic generated key and the kerneli-issue.

I tried to get kerneli working with swap some time ago and it didn't work.
Has the behavour changed? In the crypto HOWTO linked on kerneli.org is 
still said that swap encryption doesn't work (but I don't know when the
last release was written).

so long & thanks for your suggestions...
