    Pibox

    Images of pre-configured Raspberry Pi operating systems.

    Pre-configured images of my Raspberry Pi operating systems, used for backup essentially, if they help anyone else, good ! These files just need flashing to the appropiately sized SD card and then booting in your Pi, no install needed. You will need to use the dd command if the SD card is the same size as the image, if larger you can flash the SD card with "Startup Disk Creator" or similar. You should be able to login with root/root and in most Raspbian releases pi/raspberry for username/password and then change the passwords for security as well as creating any new users if you plan on using them. Notes specific to each OS will be listed in the relevant README files.
