## Installation of Avahi

There should be a dedicated user and group to take control of the avahi-daemon daemon after it is started. Issue the following commands as the `root` user:

    groupadd -fg 84 avahi &&
    useradd -c "Avahi Daemon Owner" -d /var/run/avahi-daemon -u 84 \
            -g avahi -s /bin/false avahi

There should also be a dedicated priviliged access group for Avahi clients. Issue the following command as the `root` user:

    groupadd -fg 86 netdev

Install Avahi by running the following commands:

    ./configure --prefix=/usr        \
                --sysconfdir=/etc    \
                --localstatedir=/var \
                --disable-static     \
                --disable-mono       \
                --disable-monodoc    \
                --disable-python     \
                --disable-qt3        \
                --disable-qt4        \
                --enable-core-docs   \
                --with-distro=none   \
                --with-systemdsystemunitdir=no &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install

## Command Explanations

`--disable-static`: This switch prevents installation of static versions of the libraries.

`--disable-mono`: This parameter disables the Mono bindings.

`--disable-monodoc`: This parameter disables documentation for the Mono bindings.

`--disable-python`: This parameter disables the scripts that depend on Python. It also allows a regular install to complete successfully.

`--disable-qt3`: This parameter disables the attempt to build the obsolete Qt3 portions of the package.

`--disable-qt4`: This parameter disables the attempt to build the obsolete Qt4Core portions of the package.

`--enable-core-docs`: This parameter enables the building of documentation.

`--with-distro=none`: There is an obsolete boot script in the distribution for LFS. This option disables it.

`--with-systemdsystemunitdir=no`: Without it, the daemon fails to start in BLFS, which does not support systemd.

`--disable-dbus`: This parameter disables the use of D-Bus.

`--disable-gtk`: This parameter disables the use of GTK+2.

`--disable-gtk3`: This parameter disables the use of GTK+3.

`--disable-libdaemon`: This parameter disables the use of libdaemon. If you use this option, avahi-daemon won't be built.

`--enable-tests`: This option enables the building of tests and examples.

`--enable-compat-howl`: This option enables the compatibility layer for HOWL.

`--enable-compat-libdns_sd`: This option enables the compatibility layer for libdns_sd.

## Configuring avahi
