Solaris Modular Debugger Guide

The Modular Debugger (MDB) is a highly extensible, general purpose debugging tool for the Solaris Operating System (Solaris OS). The Solaris Modular Debugger Guide describes how to use MDB to debug complex software systems, with a particular emphasis on the facilities available for debugging the Solaris kernel and associated device drivers and modules. It also includes a complete reference for and discussion of the MDB language syntax, debugger features, and MDB Module Programming API.

This Solaris release supports systems that use the SPARC and x86 families of processor architectures: UltraSPARC, SPARC64, AMD64, Pentium, and Xeon EM64T. In this document the term "x86" refers to 64-bit and 32-bit systems manufactured using processors compatible with the AMD64 or Intel Xeon/Pentium product families. For supported systems, see the Solaris OS Hardware Compatibility Lists at http://www.sun.com/bigadmin/hcl/ . This docume

So, to get something like /etc/rc.local you can use the custom SMF import facility. (See the source for more information about how this actually works.)

/opt is mounted out of zones/opt by default. You can create a directory /opt/custom/smf and populate it with SMF manifests. Any manifests you put in there will be imported by SmartOS when it boots. Below is an example SMF manifest that simply starts /opt/custom/bin/postboot, a self-explanatory shell script that you can use like /etc/rc.local.

Note that it would likely be better to customise and respin your own images, as putting a bunch of platform state in the zones pool undoes some of the benefits of the ramdisk platform architecture that SmartOS has.
