While building my custom image from distclean tree I noticed that during the package "install" (running
scripts/feeds install ...
there were quite a few packages I could not relate to anything I installed. After trying one package after another I identified the victim - ddns-scripts package:
risa@gentoo-vb ~/openwrt/openwrt $ scripts/feeds install ddns-scripts

I do not know if it was the case since the beginning, but seeing things like krb5, or python, db47 (and sqlite3 together!) definitely does not seem right for something with "scripts" in the name. (Not to speak about why it needs bluez???)
Now I wonder how much of it makes it into the image.
I am running ddns with changeip provider which should be pretty simple protocol. Is there a leaner alternative?
