I develop a project for my work.
and at each big step I create backups of my entire sd. When the project will be launched
I will continue to work on it
and make my backups.
but to update the pi on the ground
I have to make an update system.
I already thought of a web server with sftp.
and the pi would come to query to see
if there is a new version.
if so, download the image.
then I have to use the command
dd bs = 1MB if = the image of = the main partition. however we can not do that on the score we use: p
so I thought of the berryboot (heard on Google: p)
but I never manipulated.
my question is: is there a configuration file that manages the choice of boot,
and can we modify it with nano to manage the next boot without having to plug the pi to a screen?
