Ok, the good news is that you can boot. The initrd generation in systemimager is broken since the beginning as it assumes that the kernel includes from the build OS have the same structures as the includes shipped with the kernel that is built for the initrd. In the past, that was the case, most supported distros were using kernel-2.6, unfortunately, now we have distros that still use kernel-2.6 (rhel-6) and distros that uses kernel 3.X (fedora-17+, ...) and thus it becomes a problem when building things like lvn that uses kernel structure. They uses the build OS structure, but runs on the psecific kernel that has different structures from the build OS. Thus lvn have problems (crash, freezes, ...). I did my best to patch the initrd component build to use as much as I can the most relevant includes, but there are some cases where it is not possible unfortunately.
I'm working on a full rewrite of the initrd template generation by using dracut. Using dractu would remove the need to use kernels that are different from the build os while keeping the advantage to support latest hardwares. The build time would be greatly reduced (no need to build a kernel and many components. The build would be reduced to specific components like bittorent client and a few other things. More over, the libs, kernel structures and binaries would be in siync each together, thus far more stable. I've started testing and I'm able to build a next-gen initrd, but I'm still unable to boot it normally as it uses systemd and I haven't yet written the logic for that (easy). I'm currently extremely buzy at preparing an OSCAR Cluster release for rhel6. Then I'l concentrate on fixing systemImager initrd template. I hope to have somethign ready before summer.

A Debian wheezy 64bits netinstall or an Ubuntu 12.04 LTS 64 bits netinstall work fine. For me a I take the default Debian kernel and initrd from the installation and i use it with PXE. The process stop when the init process try to find root partition. All is OK because i haven't changed the PXE cmdline to boot normally. So, I tried to take this kernel and one initrd created by si_prepareclient on this fresh installation. I have exactly the same problem of /init not found. I think the problem, is in the generating of the initrd but i don't know how to debug it. I have updated the BIOS. Have you an other idea ?
