I was hoping that a Sun expert would show up and tackle this question. But I guess I'll give it a try.

First, yes you modify /etc/system and reboot...no need to build a new kernel, it gets built on the up.

But your syntax looks wrong. We have stuff like:
set semsys:seminfo_semmni= 4096
in our /etc/system. Any values in the seminfo structure are going to support system v semaphores.

On hp-ux, maxuprc is the max processes per user with maybe 50 or 100 being typical values. But on Sun maxuprc is the total processes for all users and it is typically set to NPROC - 5. So while you could bump this up, it wouldn't make sense.

If you are getting "can't fork", you surely want to up NPROC. But, just as with hp-ux, NPROC is a calculated value that rides off MAXUSERS. So my guess is that you want to increase MAXUSERS, which will increase NPROC, NFILE, NINODE, NCALLOUT, and NCLIST all at once.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
