On: Bug: true and false are not Posix (2016)

[temac]

And it would actually change the historical and current behavior of exec returning ENOEXEC for 0 bytes executables (see also https://news.ycombinator.com/item?id=19081124 ) . So I am changing my mind: a binary true is better. I still prefer truths as small as possible, though :)

It can be an extra-special 0-byte executable though, running far faster than anything else, like so:

/proc/bin/true

/proc/bin/false

The exec doesn't even need to create page tables or run any non-kernel code. This is a benchmark-winning design.
