+This document contains the information about the problems user
+may have when creating tasks living in different namespaces.
+
+Here's the summary. This matrix shows the known problems, that
+occur when tasks share some namespace (the columns) while living
+in different other namespaces (the rows):
+
+ UTS IPC VFS PID User Net
+UTS X
+IPC X 1
+VFS X
+PID 1 1 X
+User 2 2 X
+Net X
+
+1. Both the IPC and the PID namespaces provide IDs to address
+ object inside the kernel. E.g. semaphore with IPCID or
+ process group with pid.
+
+ In both cases, tasks shouldn't try exposing this ID to some
+ other task living in a different namespace via a shared filesystem
+ or IPC shmem/message. The fact is that this ID is only valid
+ within the namespace it was obtained in and may refer to some
+ other object in another namespace.
+
+2. Intentionally, two equal user IDs in different user namespaces
+ should not be equal from the VFS point of view. In other
+ words, user 10 in one user namespace shouldn't have the same
+ access permissions to files, belonging to user 10 in another
+ namespace.
+
+ The same is true for the IPC namespaces being shared - two users
+ from different user namespaces should not access the same IPC objects
+ even having equal UIDs.
+
+ But currently this is not so.

+General note on [U]EFI x86_64 support
+-------------------------------------
+
+The nomenclature EFI and UEFI are used interchangeably in this document.
+
+Although the tools below are _not_ needed for building the kernel,
+the needed bootloader support and associated tools for x86_64 platforms
+with EFI firmware and specifications are listed below.
+
+1. UEFI specification: http://www.uefi.org
+
+2. Booting Linux kernel on UEFI x86_64 platform requires bootloader
+ support. Elilo with x86_64 support can be used.
+
+3. x86_64 platform with EFI/UEFI firmware.
+
+Mechanics:
+---------
+- Build the kernel with the following configuration.
+ CONFIG_FB_EFI=y
+ CONFIG_FRAMEBUFFER_CONSOLE=y
+- Create a VFAT partition on the disk
+- Copy the following to the VFAT partition:
+ elilo bootloader with x86_64 support, elilo configuration file,
+ kernel image built in first step and corresponding
+ initrd. Instructions on building elilo and its dependencies
+ can be found in the elilo sourceforge project.
+- Boot to EFI shell and invoke elilo choosing the kernel image built
+ in first step.
