Installing chrony on the MiR

[matchRos]

Thanks for the idea to install chrony via the chroot environment with a bootstick. We were able to reproduce the process successfully, but had some difficulties. Maybe you could include some additional details.

What was missing in our opinion:

• before you can chroot into the MiR-PC you need to mount the SSD:

  sudo mkdir -p /media/mir
  sudo mount /media/mir/ /dev/sda3
  sudo mount --bind /dev/ /media/mir/@/dev
  sudo mount --bind /run/ /media/mir/@/run

• After you install chrony you need to configure it to accept connections from 192.168.12.0/24. We were not able to get the laser scanners to run otherwise.

Also we found it easier to just add a second root user and use this user to do everything over SSH:

adduser USERNAME
usermod -aG sudo USERNAME

Also for us it was simpler to just install chrony using apt. Maybe this is dangerous?

sudo apt update
sudo apt -f install
sudo apt install chrony

Yes, I've seen PR #130 which is also from your group. Thanks for that, I think it's worth adding this to the README.

Yep, I was too lazy to spell it all out since there are already lots of tutorials on how to chroot into a rescue system, but I think it's good to add these instructions.

Thanks for fixing this! I didn't have this problem on the MiR100, but the MiR600 has different laser scanners.

Yep, I've done the same, just didn't include this in the README. Thanks.

No, this is fine, but it requires that the MiR PC has an internet connection.

Let's continue this discussion over at #130! :)
