I am currently trying to set up dual boot on my Mac. I installed rEFInd to its own partition (512MB), formatted as "Mac OS Extended (Journaled)". I wanted to use the same partition as my boot partition under linux. But every time I pacstrap my system, I get an error message stating that "/mnt/boot is mounted as read-only". It's probably because it can only read the mounted partition based on the filesystem I used. I read that installing it on the existing EFI partition has caused some problems for other people so I wanted to go and take the "safe route".
I want to use rEFInd to start my OS', I do not really care if it shows up on the Startup Manager provided by Apple. I just want to be able to boot into OS X if something happens and goes horribly wrong :)
Is using FAT32 as the formatting a good idea? It would allow me to mount is as rw and make it usable as my boot partition. Or how do you guys have installed rEFInd on your systems?
