I was trying to point people to the fact that the biggest problems are
technical problems and that the license discussion was done the wrong way.

Going back to the tecnical stuff:
- The NFS export interface from Linux is weird and needs
adoptation
- Linux still has the outdated "namei" inteface instead of
the more than 20 year old lookuppathname() interface
from SunOS.
- The mmap interface is extremely different
In general, the problem on Linux is that the Linux "vfs"
interface is a low level inteface, so it is most likely easier
to adopt a Linux FS to the Solaris vfs interface than vice versa.
There is nothing like the clean global vfsops and vnodeops on Solaris
but a lot of small interfaces.

I also asume that the same people who are interested in a port
will do the maintenance...

I am sure it could be done but Linux peole cannot asume that
Sun will do it ;-)
