I like the direction in general, but there are two more comments:
1. sort(1) cannot be used in rc.d/mdconfig and should not be used in
rc.d/netif because it is before rc.d/mountcritremote. It is one
of the reasons why a loop is used for fooN variables instead of
symbol table lookup.
This may be a controversial point because our installer is now
using a single partition for whole of the base system. However,
rc.d/ scripts have been implemented in consideration of / and /usr
separation and it gives configuration flexibility. I personally
think we should avoid grep, sort, etc. in scripts before
mountcritremote whenever possible, and must be used in ones before
mountcritlocal.
And another question: is the order important in practice? I am
wondering if dropping sort(1) is harmful except that the behavior
is not intuitive.
2. Please put the normalization part into a function and use it in
get_if_var(), too. Adding another code for the same functionality
makes maintenance difficult. It degrades the performance a bit
but I think maintainability is more important for that.
