I created a read-only system from this adafruit link (https://learn.adafruit.com/read-only-raspberry-pi/ ). I have a hwclock and want to change the datetime regularly. But calling
hwclock --set --date='2018-01-31 12:00:00'
results in an error, because it has to change the content of
/etc/adjtime
Do you have any idea what I could do?
In other cases, where write access was necessary I created virtual disks from RAM. But obviously this is not a good idea since it would delete everything in /etc/.
Can I do this with a symlink to another file and use a virtual disk there? If so could someone outline the steps for me. Thank you very much.
