From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You're really close, yeah .
But because like every layer is checksummed both in delivery AND when it's installed, so you can easily validate a delivered file, and it's all signed with signatures you can easily check, you can at least be assured that
the chance of problems should be reduced.
Bonus1: with a proper repo config, you can check for updates so fast. It's like the chocolatey windows repo but more formalized and usually vendor-maintained.
Bonus2: bad upgrade? Enterprise packages on Linux (long description; trust me) can be reverse-installed over what's there so you can back-revise or downgrade with almost no pain. It's a good oh-no fix. At every point you can still validate that what is there should be there, according to hard signatures at every stage.
Bonus3: grabbing os version 6.1 and upgrading to 6.5 OR just installing 6.5 fresh gives the same final content - files and services - when you're done. (almost entirely) No cruft, since package installs (because of the locking below) just install over themselves in a way Linux people just accept and windows people may freak over.
Linux bonus: Linux locks file differently; again, long description, so trust me or look it up. You can upgrade many files and services without stopping them, and then bounce a service or a host, so your patch-and-bounce process is fast, it happens after the upgrades, and is like 2 min or with systemd 3min.
