With the attendent possibility of rendering the whole thing 
unrecoverably moot?

OTOH, if this database actually does have a better way, and its mature 
and proven, then I see no reason to cripple the database people just to 
remove what is viewed as a potentially dangerous path to the media 
surface for the unwashed to abuse.

While I'm infinitely familiar with walking around and editing bits and 
bytes in a much older filesystem than ext3 (microwares os-9), there's 
no way in hell I'd try that where 200GB of data could go byby.  A 720k 
floppy can always be re-written, but not a truely huge filesystem, nuh 
uh unless you have bare metal backups.

But thats just me being a cautious old fart, but some of the database 
folks have decades of such experience and shouldn't be penalized for 
using what to them is the fastest way to do it, after all, speed is the 
very essence of a databases performance.  Its what they sell as the 
sizzle.  Methinks then that rather than give up that advantage, maybe a 
newer filesystem might be forthcoming from the db folks, one that 
preserves that perceived advantage, but only if that advantage can be 
protected from other db vendors being able to use it too.  Which would 
being up licenseing issues I'm sure, but thats another argument on 
another day.  Thats why this looks a bit like a lose-lose situation as 
it will hurt, rather than enhance, the overall linux performance.

My $0.02, adjust for inflation since 1934. :-)
