Very saturating! Actually, I was expecting some script equivalent to NanoBSD (you know what I meant) in Owl which can produce CF images like voyage linux, based on debian-live, for 32- and 64-bit archs.

Thanks for the great security work that Owl team is doing, making GNU/Linux as secure as OpenBSD! :D /z > > Alexander >
