net_open: NFS mount error=-1

now my /etc/exports looks like:
/export/sun60 -alldirs -maproot=root sun60

but i get a lot of these:
Feb 20 23:51:40 193 mountd[218]: Could not remount /export/sun60: Invalid
argument
Feb 20 23:51:40 193 mountd[218]: Bad exports list line /export/sun60
-alldirs -maproot

and then:
Feb 20 23:51:41 193 inetd[95]: mountd/rpc/udp server failing (looping),
service terminated

when i boot without nfsd on the server, mountd now accepts the exports file.
btw: server NetBSD/i386 (486) client NetBSD/sun3 (3/60)

w/o:
/etc/inetd.conf
nfs             dgram   udp     wait    root    /sbin/nfsd              nfsd
/etc/services
nfs             2049/udp

sounds like i'm doing something recursive but what??
thanx again,
