Update RPi 0 images

This is a follow-up of:

• 65

After the mission we realized a few issues with the final image (RPi0final20240308.tar) that need to be addressed:

• [x] remove /etc/network/interfaces.d/bat0.bk
• [ ] /etc/hosts needs to be updated with:
  • [ ] the correct ip for localhost (? -- currently it has 127.0.1.1)
  • [ ] the ip/name of the bridge machine (this should include sambridge1/2)
• [ ] /etc/hosts updates need to be automated in simoc-sam.py
• [ ] the MAC for the wireless-ap in /etc/network/interfaces.d/wlan0 needs to be updated to the one of the bridge machine (this might fix hostname resolution)
• [ ] fix/reconfigure NTP
• [x] remove leftover logs in /home/pi/logs
• [ ] double-check missing dependencies (in particular avahi)
  • [ ] apt install avahi-utils
• [ ] fix/update workarounds and TODOs introduced in the code before the mission
• [ ] update simoc-sam code in the image
• [ ] add a copy-repo-all command to simoc-sam.py and a --dry-run option

Once these issues have been addressed, a new image should be produced, using:

• sudo dd if=/dev/mmcblk0 of=file.img conv=sparse bs=512
• tar --sparse -cvf file.tar file.img

Alternatively, after creating file.img with dd, use PiShrink to reduce the size of the image:

wget https://raw.githubusercontent.com/Drewsif/PiShrink/master/pishrink.sh
chmod +x pishrink.sh
sudo ./pishrink.sh file.img
