From: Vincent Prince Date: Tue, 29 May 2018 08:00:12 +0000 (+0200) Subject: package/nss-myhostname: Add package X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d25f4ce2eea4a42210b6c7ff4fbfd8a8e8845fcb;p=buildroot.git package/nss-myhostname: Add package nss-myhostname is helpful to resolve local hostname without domain. For instance, if we set hostname to myboard and ping myboard without .local suffix, it fails if /etc/hosts stays unchanged. nss-myhostname modifies /etc/nsswitch.conf file. It set myhostname resolution just after files in hosts line, for example: hosts: files myhostname mdns4_minimal [NOTFOUND=return] dns This choice comes from Debian commit [1] and Yocto recipe [2]. Also, nss-myhostname author suggests myhostname should be used as a backup and appended at the end of hosts line. Both choices are valid. Discussion on Debian bug tracker [3] gives some details on issue that may occurs using nss-myhostname (see fqdn). Note nss-myhostname is already included in systemd, so ensure is conflicts with it.
