lx(5) Standards, Environments, and Macros lx(5)NAMElx - Linux branded zone
DESCRIPTION
The lx brand uses the branded zones framework described in brands(5) to
enable Linux binary applications to run unmodified on a machine with a
Solaris Operating System kernel.
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. The
brand supports the execution of 32-bit Linux applications on x86/x64
machines running the Solaris system in either 32-bit or 64-bit mode.
Supported Linux Distributions
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.
Configuration and Administration
The lx brand supports the whole root non-global zone model. You cannot
use the inherit-pkg-dir resource with the lx brand. All of the required
linux packages are installed into the private file systems of the zone.
The zonecfg(1M) utility is used to configure an lx branded zone. Once a
branded zone has been installed, that zone's brand cannot be changed or
removed. The zoneadm(1M) utility is used to report the zone's brand
type and administer the zone. The zlogin(1) utility is used to log in
to the zone.
Application Support
The lx zone only supports user-level Linux applications. You cannot use
Linux device drivers, Linux kernel modules, or Linux file systems from
inside an lx zone.
You cannot add any non-standard Solaris devices to a Linux zone. Any
attempt to do so will result in a zone that zonecfg(1M) will refuse to
verify.
You cannot run Solaris applications inside an lx zone. Solaris debug‐
ging tools such as DTrace (see dtrace(1M)) and mdb (see mdb(1)) can be
applied to Linux processes executing inside the zone, but the tools
themselves must be running in the global zone. Any core files generated
are produced in the Solaris format, and such files can only be debugged
with Solaris tools.
