I'm really curious as to what you think about Bedrock Linux. In short, it's a meta-distribution that allows you to piece things together from other distros; eg a stable debian core with cutting edge software from the AUR. It can be hijacked onto most installs, and it seems really useful, and it seems to be making leaps and bounds in progress.
It's got some nice beginner friendly usage instructions, but to be honest the only thing I'm worried about is jacking up my install. What do you think?
