I bet you can script it. But for that first you need to know enough about it. That's where the trouble comes in getting started. E.g., a colleague suggested me to put "noatime" into my fstab. Now you might say that's about 5 seconds. But if you don't know what it is and you take responsibility for your system, then what you first do is read about it. So I spent about 10 hours reading and discussing about noatime and then decided not to put it into my fstab because I learned that the default is already "relatime" which is a little slower but much more compatible with some tools. Instead of 10 seconds I've spent 10 hours and in the end didn't change my config at all.

That's what I would expect when I get started scripting the setup myself. If I don't do it then using a sensible, community decided default would be better than doing something without investigating. Would you agree?
