[arch-general] Cannot no longer resolve local hostname with the new nsswitch.conf

[Chi-Hsuan Yen]

Hi Arch enthuasiasts,

With testing/filesystem 2016.11-2, I can no longer use my local hostname to
acess services on the local machine. For example:

$ hostname
PC12574

$ ping PC12574
ping: PC12574: Name or service not known

Seems changes in nsswitch.conf [1] does the effect. If I change the hosts:
line in nsswitch.conf back to the old configuration "files resolve
mymachines myhostname", or remove the [!UNAVAIL=return] part from this
line, ping works fine:

$ ping PC12574
PING PC12574(PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0)) 56 data bytes
64 bytes from PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0): icmp_seq=1 ttl=64
time=0.025 ms
64 bytes from PC12574 (fe80::ae22:bff:fe77:e20b%enp3s0): icmp_seq=2 ttl=64
time=0.078 ms

Is it a bug? Or such a usage is just a non-standard coincidence?

Thanks for any help.
