tftproot sollte eigentlich /var/lib/univention-client-boot sein. Funkionieren sollte aber auch /tftproot/linux. Was ist in /etc/inetd.conf konfiguriert?
cat /etc/inetd.conf
EDIT: Vermutlich fehlt in /var/lib/univention-client-boot der Symlink zu memtest
Danke für deine Rückmeldung. Hier die gewünschten Infos:
