I just checked and Quagga’s documentation doesn’t say anything about its
library.  Is it an internal library or something really exposed to

(BTW, I should note that this patch of David’s is part of his work to
support Linux containers, with a longer-term goal to support GNU/Hurd,
but that’ll be different interfaces anyway.)

As I wrote, the low-level socket interface cannot be outside of libguile
because at least ‘make-socket-address’ and friends need to cooperate.
However, libnl bindings could indeed be outside of Guile.
