NAME
     lx - Linux branded zone

DESCRIPTION
     The lx brand uses the branded zones framework  described  in
     brands(5) to enable Linux binary applications to run unmodi-
     fied on a machine with a Solaris Operating System kernel.


     The lx brand includes the tools necessary to install a  Cen-
     tOS  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.
     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  debugging 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.
