So, as the title says, I want to try bedrock linux, but I have a couple questions.

1. can I get the GPU drivers and the kernel from fedora, and all the other software from other repos, like tumbleweed, without running into incompatibilities? If there is the risk of running into incompatibilities, how can I achieve a similar result(stable kernel and drivers, leaning edge rolling packages)? Is it even possible to achieve such thing easily?
2. do I choose any init system I want or is there a default? is it hard to change it?

my skill level with linux is about able to use gentoo level, if that can help define what hard could mean to me.
