(sorry, something went wrong with my message there) Hi Leo and Gábor,
I just thought of this patch again today, but Leo beat me to it. I've looked into the licensing a bit more. The BSD advertising issue seems to be a misunderstanding on the part of Debian, at least as far as the author is concerned: http://www.syslinux.org/archives/2003-January/001484.html So, there's no clear license statement included in the package source, but the author's intention is to distribute the code under a permissive license, without advertising clause. I think we can use (license non-copyleft)? Without the BSD advertising issues, linking with readline should not be a problem either, so we can include readline as an input, and remove statements about readline from the description (I think the description comes from the Debian/Ubuntu package repositories?). We could reuse the description from https://git.kernel.org/pub/scm/network/tftp/tftp-hpa.git/about, something like: "tftp-hpa is a conglomerate of a number of versions of the BSD TFTP code, changed around to port to a whole collection of operating systems. The goal is to work on any reasonably modern Unix with sockets." WDYT? Thomas
