I agree with the barking up the wrong tree, building a physical tree in
tables doesn't sound right
given that you will have to create a new branch in the tree when a new
version/variation of ubuntu comes out.
Also think about how you are going to do basic queries like listing all
known unix variants; if that is hidden in the table names
then you'll have to issue DDL queries to do the work of SELECT queries,
which just sounds wrong to me.
I'd go for a tree, possibly using recursive CTE's to dig it.

I suspect you are barking up the wrong tree ;)
You are probably better off incorporating something like the "ltree"
type
to encode the taxonomy.

I haven't had a chance to leverage it myself but the concept it
embodies
is solid.
