Fix bug #405271 (thanks to Ogelpre) to update /etc/timezone wherever we say to update /etc/localtime as it is /etc/timezone that is the master, read by timezone-data to update localtime

18     <p>
19     You first need to select your timezone so that your system knows where it is
20 neysx 1.5 located. Look for your timezone in <path>/usr/share/zoneinfo</path>, then copy
21     it to <path>/etc/localtime</path>. Please avoid the
22 vapier 1.1 <path>/usr/share/zoneinfo/Etc/GMT*</path> timezones as their names do not
23 neysx 1.5 indicate the expected zones. For instance, <path>GMT-8</path> is in fact
24     GMT+8.

43     <p>
44     The core around which all distributions are built is the Linux kernel. It is the
45     layer between the user programs and your system hardware. Gentoo provides its
46     users several possible kernel sources. A full listing with description is
47     available at the <uri link="/doc/en/gentoo-kernel.xml">Gentoo Kernel
48     Guide</uri>.
49     </p>

52 nightmorph 1.3 For ARM systems, we will use <c>gentoo-sources</c> (contains additional patches
53 neysx 1.12 for extra features).
54 vapier 1.1 </p>
55    
56     <p>
57 nightmorph 1.3 Now install it using <c>emerge</c>.

63    
64     <p>
65     When you take a look in <path>/usr/src</path> you should see a symlink called
66     <path>linux</path> pointing to your kernel source. In this case, the installed
67     kernel source points to <c>gentoo-sources-<keyval id="kernel-version"/></c>.
68     Your version may be different, so keep this in mind.

83     <body>
84    
85     <p>
86     Manually configuring a kernel is often seen as the most difficult procedure a
87     Linux user ever has to perform. Nothing is less true -- after configuring a
88     couple of kernels you don't even remember that it was difficult ;)
89     </p>
90    
91     <p>
92     However, one thing <e>is</e> true: you must know your system when you start
93     configuring a kernel manually. Most information can be gathered by emerging
94     pciutils (<c>emerge pciutils</c>) which contains <c>lspci</c>. You will now
95     be able to use <c>lspci</c> within the chrooted environment. You may safely
96     ignore any <e>pcilib</e> warnings (like pcilib: cannot open
97     /sys/bus/pci/devices) that <c>lspci</c> throws out. Alternatively, you can run
98     <c>lspci</c> from a <e>non-chrooted</e> environment. The results are the same.
99     You can also run <c>lsmod</c> to see what kernel modules the Installation CD
100     uses (it might provide you with a nice hint on what to enable).
101     </p>
102    
103     <p>
104     Now go to your kernel source directory and execute <c>make menuconfig</c>. This
105     will fire up an ncurses-based configuration menu.
106     </p>
107    
108     <pre caption="Invoking menuconfig">
109     # <i>cd /usr/src/linux</i>
110     # <i>make menuconfig</i>
111     </pre>
112    
113     <p>
114     You will be greeted with several configuration sections. We'll first list some
115     options you must activate (otherwise Gentoo will not function, or not function
116     properly without additional tweaks).

126     Due to the highly specific nature of the embedded, we'll cover known
127     configurations for boards here. If your machine is not listed, then you should
128     visit the respective community website to figure out how to properly configure
129     your kernel.

149     Remember that EXT2 support is required for the boot partition as that is the
150     only filesystem that the bootloader can read reliably. Otherwise, the only
151     filesystem that has been tested is EXT3 but your welcome to try your luck with
152     the others ;).

262     the configuration and start the compilation process:

271     When the kernel has finished compiling, copy the kernel image to
272     <path>/boot</path>. Use whatever name you feel is appropriate for your kernel
273     choice and remember it as you will need it later on when you configure your
274     bootloader. Remember to replace <c><keyval id="kernel-name"/></c> with the
275     name and version of your kernel.
