Similarly, a lot of decisions are mostly done out of necessity
[i.e. #SystemD doesn't fit into 1440kB]

or due to licensing conflicts
[i.e. #grsec / #grsecurity is #paywalling access to it's sources so we won't even consider it as #FLOSS... ]

Also apparently grsec managed to get their #Wikipedia [article wiped](
https://en.wikipedia.org/wiki/Grsecurity ) so [WaybackMachine to the rescue]( https://web.archive.org/web/20190429055854/https://en.wikipedia.org/wiki/Grsecurity )...

So yeah...
I hope that answers the question...

grsecurity

grsecurity is the only drop-in Linux kernel replacement offering high-performance, state-of-the-art exploit prevention against both known and unknown threats.

@ffeth et en parallèle avec un bot nommé #grsec qui bloque avec des règles simple, mais où on vend les patchs qu'à ceux qui paye ? :D
