I do. Even if the Linux distribution in question theoretically supports a certain feature you are: 1. Not guaranteed that the development headers are installed. As a specific example: Debian ships systemd (and by extension libsystemd) by default. But I would not be able to compile HAProxy with USE_SYSTEMD without installing libsystemd-dev first. 2. Not guaranteed that the user is interested in certain features. I guess most are interested in OpenSSL support, but Lua might be more questionable. Why should I carry the Lua interpreter along when I'm not using Lua scripts anyway? Personally I would leave Lua out on most of my servers if I would compile my own HAProxy . This is because I realized, by doing stupid but fun things with Lua, that Lua support is way less reliable than HAProxy's C code. Possibly because most people don't need Lua and thus it gets less exposure in production. (1) could be solved with feature detection (e.g. autoconf, but you probably don't want to touch that). (2) not so much. Both could be solved with some kind of wizard that asks the user what they want and detects the appropriate options and flags based on the system. I believe something similar exists for the Linux kernel (I never compiled my own kernel). Best regards Tim Düsterhus  Big if there. I'm super happy with the job the Debian HAProxy team is doing by providing a separate APT repository for the newest versions.
