Yep. Beta 5 installs and boots up perfectly well.
I did manage to boot RC2 in single user mode. I then did the remaining configuration steps (netconfig, alsaconf, X, etc...) and had no problem doing any of it. I rebooted, trying both tui (run level 2) and run level 4. The result is the same: it hangs at configuring localhost even though the network is now configured normally. In addition when it performs coldplugging it does produce a number of errors (permissions, files not found, etc...) and hangs for quite a while before moving on to the rest. This doesn't happen on SOHO, what I'm running now.
It looks like you still have some issues to work through. Let me know if I can test anything else.
