I want to stop using macports, and use homebrew instead, I have been reading on their approach and it makes more sense to me. Now, I don't care much about having to reinstall my packages, even if some of them might not exist yet -- apparently, creating a new formula is straightforward.
But I'm a bit concerned about data which is installed in system-owned directories, like the data in MySQL or PostgreSQL. I'd like a bit of advice on how to proceed so as to have the less amount of problems migrating data from one installation to another.
I'm also curious about start scripts for daemons. Macports have complicated wrappers for launchd, but I don't know how homebrew manages that aspect. Can anyone clarify this for me?
Also, any generic advice you can provide regarding this migration will also be welcome. Things to look for, what to avoid, etc.
