I have been looking thought the kernel build tree and have a few   
questions:

To get Solaris compatibility, do I just have to have the compat_svr4   
option in the config file?

Assuming svr4 mode will take care of Solaris code, how should I setup the   
directory for Solaris under the emul directory?

Looking through files.i386, in the Compatibility Modules section, there   
is no file reference for iBCS-2 compatibility mode, why?  I've seen   
compat_ibcs2 referred to in several of the sample config files.

Is the something documenting the setup and usage of compatibility   
modules?
