No, the ./ isn't part of the name, just the path and I don't have 
another one named "rm -rf" LOL.  However lpstat with no arguments 
reports the error and my file does get written to the spool dir, so 
that's not a problem.  I read some old stuff about printcap and (at 
least in the old days circa 2000) each entry required a field sd= or 
something that told it where to write files for printing.  I don't think 
my printcap does that, but since it gets replaced at every boot, I'm not 
going to try to change it directly.
