Every time I update, I see the following:
$ apt list --upgradable Listing... Done cloud-init/zesty 0.7.9-90-g61eb03fe-0ubuntu1 all [upgradable from: 0.7.9-0ubuntu1~16.10.1]
and when upgrading
The following packages have been kept back: cloud-init
What is the package for and why is it held back?
DigitalOcean’s FAQ contains an entry on CloudInit:
What is CloudInit?
CloudInit is a process enabled on recent DigitalOcean images that is able to pull down and process information from metadata. When the Droplet boots for the first time, the CloudInit program executes the script it finds in the user-data field, providing users the opportunity to automate the initial configuration of their servers.
but I am not much wiser. Apparently, it is used during the initial boot but is it safe to remove it afterwards?
