CentOS7, after rpm -ivh netatalk-3.1.7-0.1.fc22.src.rpm
no ~/rpmbuild/SPECS/netatalk.spec at all.

my mistake, I used sudo to run rpm.

One more thing, based on ArchLinux wiki, netatalk 3.x uses /etc/netatalk/afp.conf only, afpd.conf and AppleVolumes.default are used by netatalk 2.x, so it seems unnecessary to create the later two files in your script.

Great script, thank you for sharing! To get this working on a Centos 7 Minimal, the only change i had to make was on line 70:

systemctl enable avahi-daemon.service

And all fully working, thanks for sharing!

fixed it here on my fork:

updated for netatalk 3.1.10:
https://gist.github.com/vimusr/8a310f09a38ae9b50be788a8438af310

Thanks all! This helped me get the newer netatalk working for my wife's Time Machine backups.

I compiled the src rpm on a centos 7 machine and installed it on the time machine host, another centos 7 machine. Everything worked fine -- anybody know why a regular rpm for netatalk is not available?

updated for netatalk 3.1.12:
https://gist.github.com/aidmax/556d6888397186b30862f7445d722af0

updated for netatalk 3.1.12-10 & backup patch change to /home when this fs is bigger:
