There are quite many cases where  your hardware and system clock have different values (especially when you are dual booting with windows) . But let’s start with the beginning;

There are two main clocks in a Linux system;

The System Time: This is the time kept by a clock inside the Linux kernel and driven by a timer interrupt. It has meaning only while Linux is running on the machine.

The Hardware Clock: This is a clock that runs independently of any control program running in the CPU and even when the machine is powered off.

As stated previously kolga offers a variety of gentoo services (remember the gentoo propaganda ). The main gentoo services offered are;

• portage tree rsync server
• the whole gentoo dist (current) file tree (yeah the whole 120Gbyte file tree) needed for updates and normal install

Both of the trees are synced with the gentoo server 4 times a day (@ 0100 , @0700, @1300, and @ 1900) In order to use the gentoo services offered you have to follow these steps (need superuser privileges);

1. Setup the portage tree sync
   1. This is done by editing file /etc/make.conf
   2. alter the SYNC variable depending on the dns resolves you are capable of
   3. you may use one of the following statements (you may use the last if you don’t have pwmn dns lookups);
      1. SYNC=”rsync://gentoo.kolga.pwmn/gentoo-portage”
      2. SYNC=”rsync://gentoo.korki.pwmn/gentoo-portage”
      3. SYNC=”rsync://10.140.4.1/gentoo-portage”
2. Specify the internal wireless mirror to use for source files retrieval
   1. again edit file /etc/make.conf
   2. alter the GENTOO_MIRRORS variable with one of the following (determine by the result of you DNS lookups the safe choice is always the third );
      1. GENTOO_MIRRORS=”http://gentoo.korki.pwmn ftp://gentoo.korki.pwmn”
      2. GENTOO_MIRRORS=”http://gentoo.kolga.pwmn ftp://gentoo.kolga.pwmn”
      3. GENTOO_MIRRORS=”ftp://10.140.4.4″
3. Test if everything went ok with;
   1. Test if you can sync with the local portage tree with;
      1. # emerge –sync
   2. Test if you can download sources with;
      1. # emerge -vat gentoolkit

The Gentoo Linux operating system (pronounced /ˈdʒɛntuː/) is a Linux distribution based on the Portage package management system. The development project and its products are named after the Gentoo penguin. Gentoo package management is designed to be modular, portable, easy to maintain, flexible, and optimized for the user’s machine. Packages are normally built from source code, continuing the tradition of the ports collection, although for convenience, some large software packages are also available as precompiled binaries for various architectures. (from wikipedia)

This is my current distribution, and it is one of the coolest I’ve ever seen.

Its main disadvantage is the constant building and the cpu cycles wasted. But this its main advantage also! Who else may claim that his system is as unique as his/her fingerprint? I can This is not just a poser moto. It is the heart of everything! How many times haven’t you tried to upgrade your distro from one version to another and the rpm databases failed? How many times did your mysql failed during a package manager decided upgrade? Well no more with this distro. Everything works as they ought to, though you may have to compile something every once and while

It Just Rocks
