freebsd stable - May 2003 - problems exporting ext2fs partitions in 5.0-RELEASE-p7

from my fstab file:
/dev/ad7s1              /mnt/fileserv   ext2fs  rw              0       0

from my exports file:
/mnt/fileserv/mp3  -mapall=netuser -network 192.168.1.0 -mask 255.255.255.0

when mountd starts up, or is HUP'd:

kernel: ext2fs doesn't support the old mount syscall
mountd[360]: could not remount /mnt/fileserv/mp3: Operation not supported
mountd[360]: bad exports list line /mnt/fileserv/mp3 -mapall=netuser -network
192.168.1.0 -mask 255.255.255.0

There was a thread about this problem late last year on freebsd-current, (
http://docs.freebsd.org/cgi/mid.cgi?db=irt&id=20021128064335.GA43060@hackerheaven.org
) but the problem never reached a conclusion.  I was wondering If there was any
solution in sight.

Thanks,
Matt
