[CLUE-Tech] DHCP and DNS

[Joe Linux]

Why do educational officials always insist upon one size fits all?  It 
seems to be an educational administrator a prerequisite is a total lack 
of creativity and individuality.  What happened to academic freedom and 
school choice, and the independence from a central administration within 
an individual school unit?  I ask this on behalf of Libranet which I 
used for about a year (1.9).  It was the finest computer system I ever 
owned.  Perhaps it would be better for the robotic group think 
administrators to learn about Libranet than for you to be forced to 
change distributions.
