NetBSD has been a labor of love for a long, long time.
In the mid-90's I was a teenager with a 486-25 on a desk in a closet running NetBSD 0.9-1.0, connected to 10base2 going to my dad's office where there was a computer that dual booted to Linux. I learned so much from those systems; systems programming, how to really use the C programming language, sysadmin skills, reading network traces. A whole part of who I am today derives from those early experiences trying to figure out what the $## was going on while tracking -CURRENT.
