Only the shared-IP network configuration is supported in an lx branded zone.
The chroot command is not supported in a Linux zone. If used on a process, that process would no longer be able to see the Solaris libraries it needs to run.
Although you can configure and install lx branded zones on a Trusted Solaris system that has labels enabled, you cannot boot lx branded zones on this system configuration.
You cannot add local Linux file systems using the fs resource property of the zonecfg command.
