There are several reasons for using PFSs.


Matt - you've re-invented Ramphotyphlops braminus:

Weigh this:

PFS = Parthenogenetic File System

hammer pfs-master = select a host.

hammer pfs-slave = induce ovulation.

hammer mirror-copy = self-inseminate the egg, provide nutrients to
		     grow a clone with the instincts of the parent.

hammer mirror-stream = continue growing/educating the child.
   While growing, deny it independence.
   (parent has r/w, others can see but not touch = no deviation)

hammer pfs-upgrade = hatch the egg, grant adulthood.

HAMMER fs structure - DNA if you will - must be precisely replicated in core form before any body-mass (files) save its own 'schema' can be added. Notochordata grow the spinal chord, THEN 'bud' the organs. The nerve-'tree' remains connected, trunked back to the brain, enforces order, reports environment.

Snapshotting, reblocking, pruning are comparable to our nightly sort, merge, index, and re-write of short-term memory to long-term memory.

So we're not really growing a Ramphotyphlops here.

We're growing the indexed storage portion and the storage/retrieval mechanism ..... of a brain.

Proven pattern among Odontata, too:


. .. so this file system could live a very, very long time......

Wonder how long before it grows wings....

. ...or an appetite...
