Unneeded Apps
The apps below can be removed in most cases as they are needed for my projects and take up valuable SD drive space.

tail -f /var/log/messages- handy command to look at system messages.
-
sudo blkid- produces: /dev/sda1: UUID="8dd06116-a29c-459f-9002-c1cccd7892d5" TYPE="ext4" PARTUUID="eb5e7935-01"
- Used that output to add the following like to
/etc/fstab: (Note: messing this up will brick the Pi) --PARTUUID=eb5e7935-01 /media/usb ext4 defaults 0 0 - rebooted and the drive was automounted to /media/usb
Swap
https://raspberrypi.stackexchange.com/questions/70/how-to-set-up-swap-space
Raspbian uses dphys-swapfile, which is a swap-file based solution instead of the "standard" swap-partition based solution. It is much easier to change the size of the swap.
The configuration file is:
/etc/dphys-swapfile
The content is very simple. By default my Raspbian has 100MB of swap:
CONF_SWAPSIZE=2000
If you want to change the size, you need to modify the number and restart dphys-swapfile:
sudo /etc/init.d/dphys-swapfile restart
Edit: On Raspbian the default location is /var/swap, which is (of course) located on the SD card. I think it is a bad idea, so I would like to point out, that the /etc/dphys-swapfile can have the following option too: CONF_SWAPFILE=/media/btsync/swapfile
Hostname
Reset the hostname of the RPi with these commands:
sudo nano /etc/hostname
sudo nano /etc/hosts
sudo reboot
hostname
Alternatively, can now use: sudo raspbi-config to set the hostname.
