Sparc Solaris 10 Jumpstart Flar DVD - Part 1
The Solaris Flash installation feature enables you to use a single reference installation of the Solaris OS on a system, which is called the master system. Then, you can replicate that installation on a number of systems, which are called clone systems. You can replicate clone systems with a Solaris Flash initial installation that overwrites all files on the system or with a Solaris Flash update that only includes the differences between two system images. A differential update changes only the files that are specified and is restricted to systems that contain software consistent with the old master image.
I ran into several issues trying to create such a DVD when following the standard Google results so I thought I'd summarize my experiences. This is a work in progress- I might hit a brick wall at some point, but I hope not.

Sun Apache2 breaks PHP?
This post isn't going to solve anyone's problems but maybe someone will solve mine. I recently compiled and packaged a new release of php4 (4.4.7) for use with Sun's Apache2 (Solaris 10 11/06 patched). Unfortunately for some very strange reason, Apache segfaults whenever it tries to server a page. It segfaults even if the page has no php involved and only if the php module is loaded.
Howto resize or shrink UFS partitions
A friend of mine asked me the other day if there was such a thing as Partition Magic for Solaris. Apparently, someone had installed a system on a single slice and their security team was requiring a separate partition for the DB.
