Arch Linux

Description:

Latest update to systemd package on 2016-12-09 19:34 UTC changed the /etc/nsswitch.conf file as per the feature request 51709 (https://bugs.archlinux.org/task/51709) as follows (left previous, right latest):

passwd: files | passwd: compat mymachines systemd
group: files | group: compat mymachines systemd
shadow: files | shadow: compat
hosts: files dns myhostname | hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname

However, the command "hostname -i" throws: "hostname: gethostbyname: Unknown host" and the error is resolved only by restoring the "hosts: *" line (however the "systemd" version of the config file is changed then).

strace output shows following "open" calls:

open("/usr/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
open("/etc/resolv.conf", O_RDONLY|O_CLOEXEC) = 3
open("/etc/nsswitch.conf", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libnss_files.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/etc/host.conf", O_RDONLY|O_CLOEXEC) = 3
open("/etc/hosts", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libnss_mymachines.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libresolv.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libcap.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/librt.so.1", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libm.so.6", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libpthread.so.0", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libnss_resolve.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libdl.so.2", O_RDONLY|O_CLOEXEC) = 3
open("/usr/lib/libnss_dns.so.2", O_RDONLY|O_CLOEXEC) = 4

Additional info:
* package version(s): 232-6
* config and/or log files etc. : /etc/nsswitch.conf
