Description of problem:
netdump client always try to create magic file into /var/crash/magic,
even though netdump server specify custom dump dir.

Version-Release number
netdump-0.7.16-15

How reproducible:
Always, if netdump server specify custom dump directory.


Steps to Reproduce:
Follow the KB (https://access.redhat.com/kb/docs/DOC-63704),
create a netdump server with custom dump directory.

1. Configure netdump server.  Specify --dumpdir in /etc/sysconfig/netdump-serer.

ex.
SERVER_OPTS="--dumpdir /test/crash"

2. Start netdump server .

3. Start netdump client

4. Crash netdump client.

  
Actual results:
netdump client created magic file under /var/crash/magic/IP 
everytime netdump client started.

Then when the system crash by SYSRQ key, the netdump client sent
syslog file to /test/crash/IP/log.
But no vmcore file or vmcore-incomplete file were saved.

magic file under /test/crash/magic/ip was not updated all the time.

I see "Got invalid magic number (ff6b28649e61e512) from client IP " 
in messages. 

Expected results:
The vmcore file is saved into custom dump directory.


Additional info:
The root cause is, path to storing magic file is FIXED value.

/etc/init.d/netdump 

start ()
{
        *)
    	    ssh -x -i /etc/sysconfig/netdump_id_dsa netdump@$NETDUMPADDR echo "$MAGIC2$MAGIC1" \> /var/crash/magic/$LOCALADDR
}

Modify the path to /test/crash/magic/$LOCALADDR, and re-start the netdump
client again.  Then crash the system.  The vmcore was generated succesfully.

Also, propagete() need to be fixed.
