Kompilieren der aktuellen bluez-sourcen:

git clone https://git.kernel.org/pub/scm/bluetooth/bluez.git
./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --enable-library --with-systemdsystemunitdir=/lib/systemd/system --with-systemduserunitdir=/usr/lib/systemd
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-library --disable-systemd

Build und Konfiguration gemäss Linux from scratch:

git clone https://git.kernel.org/pub/scm/bluetooth/bluez.git
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-library --disable-systemd
make
sudo make install
sudo ln -svf ../libexec/bluetooth/bluetoothd /usr/sbin
sudo install -v -dm755 /etc/bluetooth
sudo install -v -m644 src/main.conf /etc/bluetooth/main.conf

Den Bluetooth-Daemon automatisch starten und stoppen:

wget http://www.linuxfromscratch.org/blfs/downloads/svn/blfs-bootscripts-20140827.tar.bz2
bzip2 -d ...
tar xvf ...
sudo make install-bluetooth

Die Konfiguration liefert unter anderem folgenden Output für D-Bus:

checking for DBUS... yes
checking D-Bus configuration directory... /etc
checking D-Bus system bus services dir... /usr/share/dbus-1/system-services
checking D-Bus session bus services dir... /usr/share/dbus-1/services

Den Code Kompilieren und anschliessend installieren:

make
sudo make install
sudo ln -svf /usr/local/libexec/bluetooth/bluetoothd /usr/sbin

libtool: install: /usr/bin/install -c profiles/cups/bluetooth /usr/lib/cups/backend/bluetooth
 /bin/mkdir -p '/etc/dbus-1/system.d'
 /usr/bin/install -c -m 644 src/bluetooth.conf '/etc/dbus-1/system.d'
 /bin/mkdir -p '/usr/share/dbus-1/services'
 /usr/bin/install -c -m 644 obexd/src/org.bluez.obex.service '/usr/share/dbus-1/services'
Reloaded configuration
 /bin/mkdir -p '/usr/share/dbus-1/system-services'
 /usr/bin/install -c -m 644 src/org.bluez.service '/usr/share/dbus-1/system-services'
 /bin/mkdir -p '/usr/include/bluetooth'
