Agreed. When I first started dealing with Unix professionally (1995, I started playing with Unix-like OSes almost 10 years earlier) I was taught that each Unix command does one thing and does it well. That simplicity is one of the core strengths of Unix (and Unix-like) OSes. With the popularization of Linux I see many movements towards a "dumbing down" of the OS, making it behave more like more common OSes, even if those changes make it less robust and flexible. One of the reasons I choose FreeBSD over Linux in many cases is that FreeBSD is closer to the roots of Unix in terms of keeping things simple and reliability being more important than convenience. Disclaimer: I spent most of my time between 1995 and 2012 managing Solaris systems. An occasional Linux system would crop up. When I started really looking at FreeBSD in 2012 (I wanted ZFS and OpenSolaris / OpenIndiana / NexentaCore / Illumos did not support my hardware) I was very happily surprised that it "felt" like a grown up OS and not the toy that many Linux distributions feel like to me. -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company
