Title pretty much says it all really; I ran some updates today and one was for cloud-init, which prompted me to update
/etc/cloud/cloud.cfg. I opted to err on the side of caution and just leave the one I had in place, but what I'm wondering is; does it matter if I update this file on an already configured instance? Should I leave it as-is, or is it better to update to the latest version?
I haven't made any changes to the file, but it does come from an older US-East-1 setup that I migrated, so I'm using
dhc-user as the default user account, rather than
ubuntu. I assume that having the file changed to the new default of
ubuntu shouldn't impact my ability to sign in as
dhc-user as I do now, but I'm not at all familiar with what exactly
cloud-init does; is it just for new instances?
