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.

Upgrade vs Reinstall (lemmy.world)

I'm a generalist SysAdmin. I use Linux when necessary or convenient. I find that when I need to upgrade a specific solution it's often easier to just spin up an entirely new instance and start from scratch. Is this normal or am I doing it wrong? For instance, this morning I'm looking at a Linux VM whose only task is to run Acme.sh to update an SSL cert. I'm currently upgrading the release. When this is done I'll need to upgrade acme.sh. I expect some kind of failure that will require several hours to troubleshoot, at which point I'll give up and start from scratch. I'm wondering if this is my ignorance of Linux or common practice?

It depends on what you need to upgrade/do. I usually upgrade stuff, but at the same time I also have templates in case I quickly need to spin up something new.

If that's the case, I seed the new instance whatever conf files are needed and I am up and running quickly. Consider that in my work environment we rarely use containers (more of a philosophy at this point than a real reason, since we also have a relatively big K8s cluster for big data).
