what is "figlet"? I know "fillet", "piglet" and even "aiglet" but not
"figlet".

which is enabled in 100%-epsilon of the cases (i.e. except some

No, that particular file is readable by all 0644.

human-readable interfaces in /proc are the right thing to have. No point
in arguing against or about it. (if it was wrong, Linus wouldn't put it
