Neither.

1.2X wherein HAMMER fs is 'experimental'

- With an allowance for 1.3X and HAMMER fs 'stable' (as in does not 
break, crash the OS, or lose data) if not yet fast. Let us not have a 
parallel to Reiserfs troubles.

I'd like to see 2.0 reserved for 'ready for prime time'. i.e. industrial 
strength stability if not (yet/ever) a speed champ on fs or SMP issues.

JM2CW - but we are having to convert servers from <another>BSD to <a 
different>BSD 'coz - for servers - performance can be addressed with 
hardware. Stability only with hours of our lives. And we grow weary of 
chasing fragile patches.
