    If you didn't reboot after calling installworld I can tell you what
    the issue is... it's simple:  init crashed because you ripped the
    binary out from under it and replaced it with a new binary.  The
    old already-running init tried to page something in and BANG!

shouldn't something in the kernel prevent such things to happen? Something like "text file busy" when writing to the file or such...

besides, I thought install creates a tmp file and renames that to the destination. Then init should still exist on disk, until last reference is closed?
