Epics Installation At Raspberry Pi From Scratch Resize Image

Shrinking the Image

• Think of Resizing
  • Why? : Since the complete size of the SD is stored as image, and sizes of SD cards vary, a resize - at least a few MB is recommended.

PiShrink

• q.v. https://github.com/Drewsif/PiShrink
1. Take out the SD card and copy the whole image (via WinDiskImager or better tools) to a linux box
2. download piShrink
   
   image='<image>' && [ "$image" != '<image>' ] && mkdir -p ~/Downloads/ && cd ~/Downloads && wget -N --no-check-certificate https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh chmod +x pishrink.sh && sudo su -c "$PWD/pishrink.sh -s ${image:?} ${image%%.img}_resized.img"
