Hi, All. This scriplet will not do what we need: preinstall scriptlet (using /bin/sh): **/usr/sbin/groupadd** -r kamailio 2> /dev/null || : **/usr/sbin/useradd** -r -g kamailio -s /bin/false -c "Kamailio daemon" \ -d /var/run/kamailio kamailio 2> /dev/null || : The cause is, that utils **groupadd** and **useradd** are located under **/sbin** directory in OEL7.x Solution: to add an **if** statement to determine which path to use, like: if [ -e /sbin/useradd ]; then ......; else .....; fi or use RPM macro to determine which EL is actually used. --- You are receiving this because you are subscribed to this thread.
