Did anybody check out
OpenNA Linux already ?
On the website:
OpenNA Linux is a full, professional quality Unix OS with rock-solid stability and industrial-strength networking. Highly secure, very fast, and modern Linux operating system, it is intended for those who want to install and run a Linux server for mission critical tasks in a high security environment.
Well I had trouble attempting to install it ... MD5 checksums were okay, so if anybody got it up and running (I'm talking about release candidate 1) please post your comments here :-)
