I need to test it or maybe someone beats me to it by looking at the
code. But either way it's equal to or better than the current default.
For btrfs, it's raid0 data, raid1 metadata.
For current default (lvm+ext4) it's linear/concat.
It's straightforward to do data 'single' which is closer to the
current default. But no matter what, you lose a drive and you can't
boot. As a UI/UX it might need to be reevaluated what the user expects
to happen when they pick two devices and automatic partitioning. I
would argue it's ambiguous and it'd be better to only allow one device
to be selected for auto/default path. But the current UI sorta makes
this difficult, and hard to convey. You're encouraged to pick the
device(s) you want first rather than a path (auto, custom, advanced),
where it's legit to pick multiple devices for custom.
I'm not sure anyone does multiple device auto partition installs though.
