NFS incompatible with Solaris jumpstart

NFS incompatible with Solaris jumpstart

[Hadmut Danisch]

Hi,

I want to jumpstart-install (initial installation of the 
Solaris operating system) a sparc machine from a linux server
with kernel 2.6.8.1.

It works when using the nfs-user-server, but the sparc hangs after 
printing the OS prompt when using the nfs-kernel-server.

Any idea in how the nfs-user-server and the nfs-kernel-server differ 
and how to fix it?

regards
Hadmut

/dev/ was a good hint. I found the problem:

When booting the Solaris system wants to write to the 
Boot environment (nasty, isn't it?).

Since the userspace daemon doesn't understand the /etc/exports syntax
of the kernel version, I wrote a different, simplified /etc/exports
for the userspace daemon. 

The userspace daemon allowed write access, the kernel version didn't. 
That was the problem.
