Not sure what you are looking for since you would not really do the same type of rebuilding of the kernel in Solaris 8 as you would in Freebsd. You can change some parameters but you don't recompile the kernel in Solaris 8. You can check the man page for system (4) for more info.

From SunSolve (note the second line):

Quote:

The SunOS[TM] 2.X kernel modules are automatically loaded when needed.This makes rebuilding the kernel unnecessary.

There are parameters for the kernel and kernel modules that can be tuned. However, it isn't necessary to change these parameters, exceptunder special circumstances.

The module variables associated with semaphores are:

Parameter Default Description
--------- ------- -----------

seminfo_semmap 10 Number of entries in the semaphore map

seminfo_semmni 10 Number of semaphore identifiers

seminfo_semmns 60 Number of semaphores in the system

seminfo_semmnu 30 Number of undo structures in the system

seminfo_semmsl 25 Maximum number of semaphores, per id

seminfo_semopm 10 Maximum number of operations, per
semaphore call

seminfo_semume 10 Maximum number of undo entries, per
process

seminfo_semvmx 32767 Semaphore maximum value

seminfo_semaem 16384 Adjust on exit maximum value

1. Enter a line in the /etc/system file, using the following
syntax:

set semsys:seminfo_variable=value

For example, to increase seminfo_semmap from the default of 10 to 20,
add the following line to the /etc/system file:

set semsys:seminfo_semmap=20

2. Reboot the system

The kernel parses the /etc/system file during autoconfiguration
and overrides the default value for the parameters specified
in this file.

DESCRIPTION

       The following commands will return a true value (exit code of 0) if you are using an instruction set that the command name indicates.

       sun	  True if you are on a Sun system.

       iAPX286	  True if you are on a computer using an iAPX286 processor.

       i386	  True if you are on a computer using an iAPX386 processor.

       pdp11	   True if you are on a PDP-11/45tm or PDP-11/70tm.

       sparc	  True if you are on a computer using a SPARC-family processor.

       u3b	  True if you are on a 3B20 computer.

       u3b2	  True if you are on a 3B2 computer.

       u3b5	  True if you are on a 3B5 computer.

       u3b15	  True if you are on a 3B15 computer.

       vax	  True if you are on a VAX-11/750tm or VAX-11/780tm.

       u370	  True if you are on an IBM(R) System/370tm computer.

       The  commands  that  do	not  apply will return a false (non-zero) value. These commands are often used within makefiles (see make(1S)) and
       shell scripts (see sh(1)) to increase portability.
