Code:

*** Quick install instructions (tested on Debian/Ubuntu only!) ***While "configure" and "make" may be run as normal user all other commandsneed to be run as root.Configure the build system:$ autoreconf -if$ ./configure \            --libdir="/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" \            --localstatedir=/var \            --prefix=/usr \            --runstatedir=/run \            --sysconfdir=/etcIt should be noted that it's suitable for testing purposes only.The script configuring the actual Debian package can be found athttps://salsa.debian.org/utopia-team/avahi/-/blob/debian/master/debian/rules?ref_type=heads.Among other things it also turns on the hardening flags described athttps://wiki.debian.org/Hardening.Build and install avahi:$ make# make install# ldconfigAdd a user and a group for avahi. (Debian specific)# addgroup --system avahi# adduser --system --no-create-home --ingroup avahi avahiAsk D-Bus to re-read its policies:# systemctl reload dbusNow start the Avahi daemon:# systemctl start avahi-daemonOptionally start the unicast DNS configuration daemon:# systemctl start avahi-dnsconfdTo start the two daemons at boot time on Debian based distributions:# systemctl enable avahi-daemon# systemctl enable avahi-dnsconfdIf you plan to use avahi-autoipd you have to create the user/group"avahi-autoipd" much the same way as "avahi".
