Processes Running in a Branded Zone

Branded zones provide a set of interposition points in the kernel that are only applied to processes executing in a branded zone.

• These points are found in such paths as the syscall path, the process loading path, and the thread creation path.

• At each of these points, a brand can choose to supplement or replace the standard Solaris behavior.

A brand can also provide a plug-in library for librtld_db. The plug-in library allows Solaris tools such as the debugger, described in mdb(1), and DTrace, described in dtrace(1M), to access the symbol information of processes running inside a branded zone.
