Well, in a dynamic world ypbind could start and wait for events that allow it to actually do something (network online, config exists, domainname set). Anyways, even after yp.conf is there after boot a manual rcypbind restart fails. Something very weird going on: lagarto:~ # cat /etc/defaultdomain ypdomainname: Local domain name not set lagarto:~ # l /etc/defaultdomain -rw-r--r-- 1 root root 40 22. M�r 16:17 /etc/defaultdomain lagarto:~ # rpm -qa --last|grep 16:17 ypbind-2.6-lp151.1.1.x86_64 Fr 22 M�r 2019 16:17:09 CET libnss_nis2-3.0-lp151.2.3.x86_64 Fr 22 M�r 2019 16:17:09 CET libclucene-shared1-2.3.3.4-lp151.2.3.x86_64 Fr 22 Feb 2019 14:16:17 CET What writes /etc/defaultdomain?
