cannot dump fs other than /

EXAMPLE:

LIST="/var /"

for j in $LIST; do
	/sbin/dump 0bBuf 48 500000 /dev/nst0 $j
done

export TAPE=/dev/st0
mt rewind

/sbin/restore is 1
. is not on the tape
Root directory is not on tape
abort? [yn] n
/sbin/restore > ls
/sbin/restore > quit

[root@dogsbody /var]# /sbin/restore is 2
/sbin/restore > ls
.:
.bash_history  dos            net            tmp--          u6 
bin            etc            opt            u1             u7 
boot           home           proc           u10            u8 
burner         info           roast          u11            u9 
cdrom          lib            root           u2             usr 
cdrom4         lost+found/    sbin           u3             var 
cdrom6         misc           tftpboot       u4 
dev            mnt            tmp            u5 

/sbin/restore > quit



Tested other way around; in thad case file 1 looks like my root,
and file 2 DOES NOT show anything.

Trouble with writing multiple tape files from Solaris client; can
see only the last in the set.  This worked OK a while ago.
Am using the no-implicit-rewind device /dev/nst0.
