At face value it looks as though you are being sarcastic (and insinuating that it’s obvious I should do what it recommends) but you are usually very polite and helpful so I am not sure.

If it were to say “You must…” rather than “You can…” I’d be happier do what it recommends without checking here.

Also, sometimes I have reported warnings here and been told not to worry about them because, for instance, a decision has been made to continue doing things a certain way despite the warning message (e.g. “You can ignore those warnings”: Warnings: overcommit_memory and Transparent Huge Pages).

I also wonder whether following the recommendation might cause some unintended consequence.
