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
