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? qvb -- pica
