Is it necessary to create a softlink "ln -s /pfs/slave /somewhere" or mountpoint "mount_null /pfs/slave /mnt/slave" to access the hammer slave?<br>
Or can i directly access the hammer slave with "cd /pfs/slave"?<br>
<br>
What about the master? The same questions as above.<br>
<br>
(Sorry for my incredibly bad english)<br>
