Reconfiguring nsswitch.conf for Avahi after changes to filesystem pkg

I have Avahi configured on my laptop and had changed the line

hosts: files dns myhostname

in nsswitch.conf to

hosts: files dns myhostname mdns4

Since updating Arch today changed nsswitch.conf, the original line now reads

hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname

Looking at the instructions on the wiki instructions at https://wiki.archlinux.org/index.php/Avahi, I found the suggested line is

hosts: files mdns_minimal [NOTFOUND=return] dns myhostname

However, this assumes the old default.

What should the line now be changed to to support Avahi? My current guess is that I want something like

hosts: files mymachines resolve [!UNAVAIL=return] mdns4_minimal [NOTFOUND=return] dns myhostname

since I almost certainly want the IPv4-only version, given the networks I use. However, I'm not sure if this is correct because I have an admittedly foggy idea of what this is doing.

I can't imagine why I was not already using the _minimal version as it seems very unlikely I need anything else. That's why I used the _minimal version in the new line I'm trying. But I am not sure if this addition is still required (but am reasonably sure something must be) or where it should be placed in the list of hosts.

Re: Reconfiguring nsswitch.conf for Avahi after changes to filesystem pkg

The Avahi page has now been updated to account for the new nsswitch.conf (thanks @nl6720). Like you, I was wondering how to properly merge the file after update. No issues with using the string there so far.
