I was curious, what's the results of the openrc update for people that have done theirs?  Is it pretty simple and "just works" or are there issues?  I'm mostly interested in x86 and amd64 since that is what I have.  Just a simple works here and I'm X86 or amd64 would be nice.  List issues if you had any.

IMO if you read the guide through before starting, and follow it during implementation, you will be fine.

That is, it works if you do it properly :)
