Fun and Profit using altsrc
===========================
-Altsrc is a generic, bcfg2-server-side mechanism for performing configuration entry name remapping for the purpose of data binding.
+Altsrc is a generic, bcfg2-server-side mechanism for performing
+configuration entry name remapping for the purpose of data binding.
Use Cases
=========
-* Equivalent configuration entries on different architectures with different names
-* Mapping entries with the same name to different bind results in a configuration (two packages with the same name but different types)
-* A single configuration entry across multiple specifications (multi-plugin, or multi-repo)

Examples
========
-* Consider the case of /etc/hosts on linux and /etc/inet/hosts on solaris. These files contain the same data in the same format, and should typically be synchronized, however, exist in different locations. Classically, one would need to create one entry for each in Cfg or TCheetah and perform manual synchronization. Or, you could use symlinks and pray. Altsrc is driven from the bundle side. For example:

- <ConfigFile name='/etc/hosts'/>

- In this case, when a solaris host gets the 'netinfo' bundle, it will get the first !ConfigFile entry, which includes an altsrc parameter. This will cause the server to bind the entry as if it were a !ConfigFile called '/etc/hosts'. This configuration entry is still called '/etc/inet/hosts', and is installed as such.
