No magic wand here, I just see it as scripts all the way down...
Creating and mounting a tmpfs and bringing up the network look pretty
much the same to me: initialization tasks orchestrated by scripts
invoking userland binaries. At this point in booting, if something fails
it's watchdog time...
Regarding read-only root fs, isn't it just a matter of restarting
svscan's logger pointing to stable storage once it is up & running?
