I don't think ZFS being added to Linux will mean Solaris loses an advantage. I

reasons for opening up Solaris was to reduce the barrier to entry for those 
wanting to use Solaris. By having ZFS included in other operating systems, the 
barrier to entry is reduced, since more people will have ZFS skills before they 
look at Solaris. Clearly there is a down side in that you can use ZFS without 
using a Sun product, but if this were a problem for Sun then they would not 
have open sourced Solaris in the first place. This is because, by open sourcing 
Solaris they make it more likely that Solaris features will be included in 
other operating systems.


Anyway, this "talk" looks a bit like the case where a boy scout is trying to
help an old lady to cross the street while the lady does not like to cross the
street at all.

Why to probably "help" people who don't like to get help?

I am in fear that Sun spends money on helping Linux to get ZFS while the
same money could better help Solaris to implement a decent pcfs or to enhance
hsfs.

Please, Joerg, let it rest. We have tried (in vain) to get hsfs/pcfs work through in an "accelerated internal fashion" but that failed, for reasons that I really don't want to go through right now.

I admit that I have not exactly put up a stellar performance there and I apologize to you for failing you when acting as internal liason for this. I could have done better, working with other internal stakeholders more intensively than I did.

But re-iterating "Sun does not want that", "Sun prioritizes wrongly", etc. etc. - it doesn't solve the underlaying issue, and it doesn't progress work towards solving these known deficits either.

I agree with you that the legacy filesystems in Solaris aren't perfect and deserve some attention. But should that attention really be drawn away from the future, from the key distinguishers of Solaris' technology ?

Quite honestly, I'd love to have ZFS on Microsoft Windows ...

I am in fear that this ends up in a license discussion.

I am in fear that someone at Sun is going to give ZFS a less free license than
it has now.
