Before opening an issue, make sure there is not a similar issue already open

Describe the problem

Updating the do-agent package makes changes to /etc/passwd. This creates unnecessary alerts from monitoring systems that monitor the /etc/passwd checksum. See this commit: https://github.com/digitalocean/do-agent/commit/cfeb60fd44c2e9f9ddca53496a906b40a36371be

Steps to reproduce

Update do-agent and then run sdiff /etc/passwd /etc/passwd-.

Expected behavior

Updating the do-agent package does not alter /etc/passwd.
