First, sorry about the systemd list, I did not know it's subscriber-only.
This is Frugalware Linux, and it's disabled by default here as well.

Sure - here is a qcow image (871M):
http://frugalware.org/~vmiklos/files/systemd.img
Here is how I started it:
qemu-kvm -vnc :0 -m 1G -hda systemd.img
$ qemu-kvm -version QEMU PC emulator version 0.12.3 (qemu-kvm-0.12.3), Copyright (c) 2003-2008 Fabrice Bellard
There are two menu entries in grub config - first is sysvinit, that boots up correctly here, you can login using root / root. The second is systemd, that just panics here almost all the time. In case it would not, use 'systemctl emergency' as root and that will trigger the bug. :)
If you need more packages in the virtual machine and the pacman package manager sounds exotic, here is a quick help:
