I've played around with Bedrock Linux for the last few hours. It looks like a really cool project.
It's not really a full distro but rather a package manager for other distros. So for example you can run 'brl fetch debian arch ubuntu' and it will install Debian, Arch, and Ubuntu on your system.
You can also run apps cross distro. So if you have gimp installed in Arch but not Debian you can still run the Arch version of gimp while logged into Debian.
