I bought a 32gb class 10 sd card to run Fedora on a laptop where I don't want to touch the hard drive.

After a bit of reading it seems it's a good idea to make sure the partition and filesystem are setup to get the most out of it (mainly around block side and erase boundaries)

So I booted to Fedora 22 Workstation and before running the installer setup a /boot and "/" partition and formatted them. Now when I'm trying to configure disks it's telling me that "You must create a new file system on the root device."

WTF?!? So what if I want to format the partition with specific options? Specifically stride and stripe-width...

Thanks,
Richard
