Subject: Re: Owl encrypted / and tcplay
Thanks to Alexancer and Alexey both for very useful info.
@Alexey: I need to encrypt /. I am quite impressed by full disk
encryption, recognized by bootloader of OpenBSD 5.3. Impressive work.
If Owl can implement somehting similar it would be wonderful. (ref:
http://ryanak.ca/planet-ubuntu/2013/03/26/Setting-up-full-disk-encryption-in-OpenBSD-5.3.html).
Actually full disk encryption is a basic requirement for me. I also
thought of installing Owl as a qemu instance of OpenBSD, but gave up
the idea of running vitualization on top of another virtualization i.e
openvz on top of qemu!
