Yaku-NS (formerly ENS)

Yaku-ns (formerly ENS) is a small footprint, trivial to configure, DNS server. While the ENS primary target was the embedded systems yaku-ns, that's derived from the ENS source code, was fixed to be a real nameserver. Lists was replaced with hash tables, zone AXFR implemented in input, fix and RFC-like behaviours added.

However while a lot of the code is already implemented the project lacks documentation, testing, and an accurate development. Anyway it is already a lot better than ENS.
PLEASE, CONSIDER YAKU-NS SPERIMENTAL CODE
Major features are:

Support for A, MX, NS, TXT, PTR, SOA in local resource records.
Additional RRs handling.
Responses cache, with optional TTL expiration.
Forwarding to multiple exteral DNS servers, with simultaneous or time-driven query.
Optional TCP zone transfer.
A in RRs shuffling.
Built-in ACL rules.
Root privileges squashing.
Chroot jail under unix systems.
Secure DNS IDs to prevent DNS forgey.
Logging.
Very simple config file.
Little binary size.
