I downloaded last night's Nightly Compose of Rawhide, burnt it to a disk (I tried it in qemu-kvm and it works) and booted it.

After quite a long time, and long pauses between reading the disk and stopping, finally a mouse pointer appears on a black background, but even after waiting 30 minutes, nothing else happens.

I switched to a different virtual terminal and typed liveinst and after a long time a line appears that the font is being loaded, but then nothing.

I rebooted the disk and this time tried liveinst -C (I think it is), to get the text-based version. This does indeed run, but when I am asked how I want to partition, it only offers to wipe my whole drive, replace an existing linux installation that it is, however, unable to locate, and some other unacceptable option, but does not allow me to select a partition that already exists that I want to use.

I also tried using liveinst as a boot parameter, with the same results as above.

The graphical liveinst might be the better option, assuming that it allows me to choose the partition I want, but X will not start.

How can I get X to start with a nightly compose and how can I install the live disk to the partition of my choice without destroying the other partitions (as I always do when I reinstall my system)?
