+====== Notes on setting up Raspberry Pi 2 ======
+This post describes the stuff I did to my Raspberry Pi 2, which is the current acting home server. These configuration steps are probably useful for everyone.
+  - Download and flash the Raspbian-lite image.
+  - Remove the following packages: ''dhcpcd5 dphys-swapfile raspi-config triggerhappy bluez*''
+    * ''dhcpd5'' interferes with ''/etc/network/interfaces'' - it makes configuring the network more complicated.
+    * ''dphys-swapfile'' configure a swap file in the root partition - I have no idea why anyone wants that.
+    * ''triggerhappy'' not entirely sure what it does, probably useless - I have never used it.
+    * ''raspi-config'' messes with your CPU frequency governor at boot, of course you want to use the ''performance'' governor.
+    * ''bluez*'' are the Bluetooth related things. I don't use Bluetooth.
+  - Wipe the unnecessary stuff in ''/etc/rc.local'', so your IP address doesn't come up in the boot screen - I found it weird.
+  - Install 'default-mta', of course you want to receive all the system emails.
+  - Install ''sysfsutils''
+      * Add the following in ''/etc/sysfs.conf'', these ensures that your CPU always runs at the fastest speed. You should be using zswap anyway.
+      * <code>
+devices/system/cpu/cpu0/cpufreq/scaling_governor = performance
+devices/system/cpu/cpu1/cpufreq/scaling_governor = performance
+devices/system/cpu/cpu2/cpufreq/scaling_governor = performance
+devices/system/cpu/cpu3/cpufreq/scaling_governor = performance
+module/zswap/parameters/enabled = 1
