ping: Name or service not known (/etc/hosts)

[gcb]

I cannot ping entries in /etc/hosts

Using the upstream ping.profile:

$ systemctl status systemd-networkd
○ systemd-networkd.service - Network Configuration
     Loaded: loaded (/usr/lib/systemd/system/systemd-networkd.service; disabled; preset: enabled)
     Active: inactive (dead)

$ systemctl status systemd-resolved
○ systemd-resolved.service - Network Name Resolution
     Loaded: loaded (/usr/lib/systemd/system/systemd-resolved.service; disabled; preset: enabled)
     Active: inactive (dead)

$ systemctl status NetworkManager
● NetworkManager.service - Network Manager
     Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled; preset: disabled)
     Active: active (running)

$ grep 127.0.0.1 /etc/hosts
127.0.0.1 testing

$ grep hosts /etc/nsswitch.conf 
hosts: mymachines resolve [!UNAVAIL=return] files myhostname dns

$ getent hosts testing
127.0.0.1       testing

$ ping testing
/usr/bin/ping: testing: Name or service not known

$ /bin/ping testing
... works fine ...
