cycletest now has decent options passed in.
I havent given any thought to exposing options thru xeno-test's command 
line.

Instead, Im thinking of adding statistics, ala latency.
for that, Im also pondering a new -g 100 option to group the tests for 
stats-calcs,
ie given: -g 100 -l 1000 -v
it would compute statistics on 10 sets of 100 cycles, and report 10 lines.
Again, this is notional, comments/feedback needed.

> -  changed the prewired -m email-addy to xenotest.output@xxxxxxxxx
email options now work w/o actually writing a file.
Also changed default location of file writes to /tmp,
they no longer get written to $PWD by default

added a -U <url>,  completely untested, but mostly lifted from LiveCD
This looks necessary, since
   my hobby-box doesnt have a working mail setup
   my laptop (and presumably yours) doesnt have a FQDN,
       which pretty well precludes sending mail to anywhere useful.
         (Id bet we could span the unwashed winbloze masses, but wheres 
the sport in that ?  ;-)

added items per RPMs email.

Im considering stripping the warning issued when CPU_FREQ ia xonfig'd
warning: CONFIG_CPU_FREQ=y may be problematic.
I have it in cuz nothing actually changes (can change) it, so its 
harmless. (I think)
Its easier than making the list complete,
and the .config dump covers the reporting.

Its reasonbly tested; we can shake out some more with some distributed 
testing
(hint - try it !)

Heres some tests I ran, files got written..

./xeno-test -T 30 -l30 -m
./xeno-test -T 30 -l30
./xeno-test -T 30 -l30 -L
./xeno-test -T 30 -l30 -N foo
./xeno-test -T 30 -l30 -LN bar
./xeno-test -T 30 -l30 -LN buzz -m
./xeno-test -T 5 -l30 -L -m
./xeno-test -T 5 -l30 -N /tmp/box- -m
./xeno-test -T 5 -l30 -N ~/trucklab/ -w2 -W 'dd if=/dev/hda1 of=/dev/null'

these are still open, but not crtical.


I hope thats everything for now,
it needs a good shakedown, and I need a beer.
