Overall, a very good summary. The Apache module is its own package,
mod_dnssd, and I'm not sure what is meant by "desktop applets" (there
are command-line tools that could be placed on a GUI desktop).
As this package is not your everyday CMMI package, it deserves a
spot in BLFS. Though not many right now probably use service
discovery - Zeroconf style networking, I can see it becoming a staple.
Many distros are shipping with Avahi.
Reasons for a BLFS page include:
1. Special user and group should be created to run the daemon.
2. Has several required dependencies and libdaemon would be a
recommended dependency.
3. Has a gazillion optional dependencies.
4. Can run a daemon requiring bootscripts (not installed in a
BLFS installation as BLFS isn't a defined "distro").
5. There are several BLFS packages that would list it as an
optional dependency.
6. There is no other 'service discovery' package in BLFS.
7. The configure command will end up being lengthy if you don't
have several of the optional dependencies installed. For
example, this command was required to build on my current
test system:
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--enable-compat-howl \
--enable-compat-libdns_sd \ #optional for KDE
--with-distro=none \
--disable-qt4 \
--disable-libdaemon \ #libdaemon would be a 'recommended'
dependency
--disable-pygtk \
--disable-mono
I'll enter a ticket for it and prepare the BLFS page. I'll wait
a couple of days before adding it to the book in case someone
comes up with a reason why it shouldn't be added.
