Source: nbd-server
Severity: normal

Dear Maintainer,

I am trying to make swap space available to diskless clients using nbd
on a squeeze network.  However, using the third option as described in
the debconf template fails: 

   You can export a real block device (for instance "/dev/hda1"); a normal file 
(such as  
   "/export/nbd/bl1"); or a bunch of files all at once. For the third option, 
you can use  
   "%s" in the filename, which will be expanded to the IP-address of the 
connecting  
    client. An example would be "/export/swaps/swp%s".

I tried "/opt/swp%s" with and without '"', and prepared the file
/opt/swp10.0.0.201 like:

    dd if=/dev/zero of=swp10.0.0.201 bs=1024k count=0 seek=64
    mkswap swp10.0.0.201

but the clients complain about not enough swap area to use on
/dev/nbd0.    

As soon as I prepare a file /opt/swp%s in the same way, swap space is
available on the client and anything works fine.  If I use the swap
damon /usr/sbin/nbdswapd from the ltsp-server package which creates 
swapfiles on the fly using inetd, it works too.

So it looks as if %s is not replaced by the IP-address of the client.
Or is there anything I missunderstood in using %s?

Best regards,

     Andi
