In the Linux Jump-Start installation steps, what is the first command to update the system on RHEL-like distributions?

The first command to update the system on RHEL-like distributions is "yum update." This command is specifically designed for managing packages on these types of systems, which include Red Hat Enterprise Linux (RHEL), CentOS, and Fedora.

When executed, "yum update" will check for the latest versions of the packages installed on the system from the repositories and will install any found updates. This ensures that your system is running with the latest security patches and software enhancements, making it more secure and stable.

On the other hand, commands like "apt-get update" and "apt-get upgrade" are used on Debian-based distributions such as Ubuntu, not RHEL-like systems. Therefore, they would not be applicable for updating a RHEL-lite system. The command "yum upgrade" is also relevant, but "yum update" is the standard command used for this process in most user documentation and common practices for updating packages. Thus, "yum update" is the most accurate choice here.
