/usr/sun/bin 消失在4.0.2

A: anyone who knows why we delete /usr/sun/bin directory in the version 4.0.2?
B: We don't.  It is now simply /usr/bin
B: The GNU commands that were in /usr/bin are now in /usr/gnu/bin
A: okay, I see, Thanks ,that's exactly my 2rd question about /usr/gnu/bin
A: thank you very much @P
C: They're also symlinked to /usr/bin/g<command>
C: so ggrep == /usr/gnu/bin/grep, gdd == /usr/gnu/bin/dd, etc.
A: good to know that @K :)
