Try to make a JeOS appliance (e.g. using SUSE Studio) of openSUSE 12.1 x86 and add a Tumbleweed repo. Than build the Live CD image and try to boot it.
You will get a boot error:
Failed to mount clic filesystem
And when you add kiwidebug=1 in boot options, you will see:
clicfs: error while loading shared libraries: libfuse.so.2: cannot open shared object file: No such file or directory
This is a critical regression in Tumbleweed. Kernel-default is in version 3.4.6-34.2 and libfuse is in version 2.9.0-3.1. Adding the older libfuse 2.8.5-16.1.2 package doesn’t work. Anybody can help?
Apart from that, the GRUB graphical menu has recently gone in Tumbleweed. Now there is a text-only mode. >:(
