This month’s install was interesting.
My original plan was to install from the KDE live iso. So I downloaded “openSUSE-Tumbleweed-KDE-Live-x86_64-Snapshot20160307-Media.iso” and wrote that to a USB. It booted up nicely, and ran well. Among other things, that suggests that the problems with persistent storage on the usb device have been fixed. It created a hybrid partition that was mounted as “ext4” instead of the “btrfs” that had been giving problems with the persistent hybrid partition.
