The kernel is not 50 megabytes, more like 5.

If the kernel is built with every possible device driver that's an awful lot of modules, but 50 megabytes still seems like an awful lot. Don't mistake the source code for the kernel itself -- you don't need the .c files to make the system boot. A light distro just gives you the binary part.

Light-weight alternative to `df` (without SNMP)

Overview: I'm looking for a way to get usage data for all mount points (UFS,VxFS & NFS) on a Solaris system. I'm starting with `df` but would like to find something that might be more light-weight. Background: Using SNMP is not an option in this case, instead I need to use basic built-in...

How to simulate light weight process (LWP)?

Hello, We had a problem on a Solaris system (SunOS 5.10) that hit LWP limit and caused fork 11 error. Now we need to come up with a script to simulate and reproduce that scenario. What would be a simple and valid way to generate lots of Light Weight Processes? Thanks, Jay

pmerge(8)						      System Manager's Manual							 pmerge(8)

NAME

       pmerge - Builds a network bootable kernel.

SYNOPSIS

       /usr/sys/bin/pmerge bootfile kernel.name new.kernel

DESCRIPTION

       The  kernel, vmunix, is not bootable over the network. The pmerge utility prepends the bootfile onto the kernel image (kernel.name) to cre-
       ate a new operating system image (new.kernel) that is bootable over the network.

       Instead of a booting a network loadable kernel, it is sometimes desired to bootstrap link a kernel over the network.  In this  case,  (ker-
       nel.name)  is the name of the sysconfigtab file on the server containing the list of modules to be loaded to the client.  These modules are
       then linked to create a bootable kernel on the client.

       The pmerge utility is used by doconfig(8) to create a bootable operating system for dataless management services (DMS)  client  systems	to
       boot over the network. The pmerge utility is automatically invoked by doconfig(8) during the kernel build process and should not be invoked
       independently.

       The pmerge utility is located in /var/adm/dms/dmsn.alpha/root/usr/sys/bin on the DMS server.
