Most likely I had installed pyparsing NOT using rpm, but from pypi.  Then I'm 
guessing that on upgrade something pulled in pyparsing.  Packaged in an 
incompatible form, causing cpio to choke.

I'm suggesting that anaconda should not quit in the middle of an update due to 
one rpm package failing to update.

IIRC, this I had another machine that failed update in exactly the same way 
(pyparsing).  (Fortunately, this time I could still boot, rm pyparsing, and 
resume, but last time was a disaster).
