I have made a little progress on a more embeddable NetBSD userland. Using ldns, <http://www.nlnetlabs.nl/ldns/>, I have replaced ISC BIND's dig(1) and host(1) utilities. I replaced dig with drill, a program that is distributed with ldns. I created a simplified host(1) command by modifying the ldns-mx.c example in ldns. The storage savings are substantial: # ls -l `which host` -r-xr-xr-x 1 root wheel 1257396 Sep 7 21:23 /usr/bin/host # ls -l `which dig` -r-xr-xr-x 1 root wheel 1269464 Sep 7 21:23 /usr/bin/dig # ls -l `which host` -rwxr-xr-x 1 root wheel 12084 Sep 21 15:57 /usr/bin/host # ls -l `which drill` -rwxr-xr-x 1 root wheel 42120 Sep 21 00:37 /usr/bin/drill # ls -l /usr/lib/libldns.so.1.2 -r--r--r-- 1 root wheel 482979 Sep 21 00:37 /usr/lib/libldns.so.1.2 You can browse the sources for my host(1) replacement here, <http://svn.cuwireless.net/svn/cuw/trunk/src/host/>. It does not work alike to ISC's host(1), but it works for my purposes. I still seek a small replacement for the ISC DHCP client and server. udhcp looks promising, but there is not a NetBSD port, yet, and it is GPL.
