As a sysadmin, I’d be weary of using something like this. Like it’s great you can go 15 years but you also have to think how much the landscape is changing in that 15 years. Are you sure your application you’re safeguarding that long will even work on new versions?

Would almost rather just deal with the normal 5-10. If anything, moving to containers or some kind of immutable distro is a better bet in the long run.
