today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and

Linux is easily portable to most general-purpose 32- or 64-bit architectures
as long as they have a paged memory management unit (PMMU) and a port of the
GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
also been ported to a number of architectures without a PMMU, although
functionality is then obviously somewhat limited.
+ Linux has also been ported to itself. You can now run the kernel as a
+ userspace application - this is called UserMode Linux (UML).
DOCUMENTATION:
version 2.6.12.2 and want to jump to 2.6.12.3, you must first
reverse the 2.6.12.2 patch (that is, patch -R) _before_ applying
the 2.6.12.3 patch.
+ You can read more on this in Documentation/applying-patches.txt
- Make sure you have no stale .o files and dependencies lying around:
only ask you for the answers to new questions.
- Alternate configuration commands are:
+ "make config" Plain text interface.
"make menuconfig" Text based color menus, radiolists & dialogs.
"make xconfig" X windows (Qt) based configuration tool.
"make gconfig" X windows (Gtk) based configuration tool.
