Yes, that's exectly what I did. The trick is going to be
getting this entropy file onto a ramdisk before the
SecurityServer opens it at boot time. I wonder if anything
else opens it and holds it open?
I also discovered that cupsd was periodically reading
from /dev/random and writing to the disk. Since I'm not
printing from this machine, and never will, I killed it.
The disk has been silent for almost 48 hours now. Now that
we've found all (?) of the houskeeping processes that are
writing to disk, maybe it's time to turn `update' back on.
If nothing's scribbling in the buffer, the sync shouldn't cause
any activity.
