[TUHS] How good a representative of System V is Solaris

[Brantley Coile]

Solaris is not pure System V.  I started working on the internals of  
System V in 1985 and I have purchased a number of Solaris boxes in the  
1990's and 2000's and while Solaris is based on the System V kernel,  
it doesn't feel like System V.
