21 # Note that it's normal for the newborn system to think rather hard at
22 # the beginning of this process (e.g. using nearly 100Mb of virtual memory
23 # and >30 seconds of CPU time on a 450MHz CPU), and unless you built the
24 # system with the :SB-SHOW feature enabled, it does it rather silently,
25 # without trying to tell you about what it's doing. So unless it hangs
26 # for much longer than that, don't worry, it's likely to be normal.
