After looking closer, i realized that the client actually achieves
mounting, it just mounts the debian mirror to another location. The
relevant lines of the mount output are:

rootfs on / type rootfs (rw)
/dev/sda1 on /target type ext3 (rw,noatime,errors=remount-ro,data=ordered)
192.168.0.1:/srv/debmirror on /target/media/mirror type nfs
(ro,noatime,vers=3,rsize=262144,wsize=262144,namlen=255,acregmin=1800,acregmax=1800,acdirmin=1800,acdirmax=1800,hard,nointr,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountproto=udp,addr=192.168.0.1)

Why is the mirror beeing mounted on the installation disk
(/target/media/mirror) ? I expected it to be mounted on /media/mirror
of the nfsroot. Did i miss something in the configuration? Or is this
the expected behaviour?

Best regards,
Thomas
