a script that is not supposed to be portable to a POSIX-only system, can be 
written in any way the host system supports. So it is not 'broken' nor 'badly 
written'. Please calm down. Ok?

no.

Please stop that nonesense, ok? Gentoo scripts are gentoo scripts. Not AIX, 
Solaris or HP-UX scripts (systems who are very arcane in a lot of aspects). 
So gentoo scripts don't need to be portable, so they don't need to be POSIX 
compliant. And since gentoo is a linux distribution and almost all linux 
distributions use the gnu-userland, gnu-compatibility is more than enough for 
portability to other linux distributions.

And some last questions: if POSIX is so great, why is there stuff 
like 'SUS', 'LSB', and why has POSIX many different versions?
