Following up ZBX-4916, Fedora/EPEL uses different system users for agent and server/proxy. The names were chosen as zabbix and zabbixsrv to minimize changes on monitored hosts; Their respective home directories being /var/lib/zabbix and /var/lib/zabbixsrv.

During installation, Zabbix creates externalscripts and alertscripts directories. These directories should be in /var/lib/zabbixsrv now. As it is now, the directories are somewhat hard-coded, being:

@datadir@/zabbix/externalscripts
@datadir@/zabbix/alertscripts
pkgdatadir = $(datadir)/@PACKAGE@

Please allow for the freedom to freely choose that directory, instead of having "zabbix" hard-coded.
