The lx brand includes the tools necessary to install a CentOS 3.x or Red Hat Enterprise Linux 3.x distribution inside a non-global zone. Versions 3.5 to 3.8 of each distribution are supported. The brand supports the execution of 32-bit Linux applications on x86 and x64 machines running the Solaris system in either 32-bit or 64-bit mode.
The lx brand emulates the system call interfaces provided by the Linux 2.4.21 kernel, as modified by Red Hat in the RHEL 3.x distributions. This kernel provides the system call interfaces consumed by the glibc version 2.3.2 released by Red Hat.
In addition, the lx brand partially emulates the Linux /dev and /proc interfaces.
Note that you must maintain a supported configuration if you add packages to an lx branded zone. See About Maintaining a Supported Configuration for more information.
