[B.A.T.M.A.N.] ipkg install batman over ssh: postinst fails

[jan@aims.ac.za]

Hi

I have a mesh running freifunk â’ˆ.6.32 nodes.
I am using the recommended batman0.2 ipkg to test it next
to OLSR. (Is there no ipkg package and source for 0.3 or 
the latest stable?)

When I did two nodes manually, I installed and set the network
migration, and saw some batman packets.

Then I went ahead and scripted an install on all the nodes (about 40).

It goes, with dropbear authorized_keys, for each node in $NEWIP:

   # batman sources
   scp root@${NEWIP}:/etc/ipkg.conf .
   patch ipkg.conf < ipkg.conf.patch
   scp ipkg.conf root@${NEWIP}:/etc/ipkg.conf
   # update
   ssh root@${NEWIP} ipkg update

   ssh root@${NEWIP} ipkg install batmand freifunk-batman
   # Next line must be done with expect else nvram not found
   # For now it will be done on reboot anyway
   #ssh root@${NEWIP} /etc/init.d/S66batman restart

The nvram command is usually not in the path over an ssh like
that (not interactive, passing the command to ssh as an argument)
thus I use /usr/sbin/nvram. In two places this fail:

The freifunk-batman package:
Unpacking freifunk-batman...Done.
Configuring freifunk-batman...//usr/lib/ipkg/info/freifunk-batman.postinst: 10: nvram: not found
//usr/lib/ipkg/info/freifunk-batman.postinst: 10: nvram: not found
Done.

And the S66batman restart, which I did manually.

Now the batman runs, has all the nvram settings, though I didn't go through
the prompt for network migration via the web interface -- I did the script
above. But there are no batman neigbours or messages shown on the info/status
pages in the web interface. Even when I reinstalled freifunk-batman two nodes manually,
that is via interactive ssh, and there was no error, I am still getting no batman
neigbours shown.

Usually I do such cases with expect, there are several places
in my freifunk install / upgrade script where I do this). 
The long term answer is clearly? a trx/bin image of our own.

In the meantime, do I have to reflash them, install batman manually
or with expect? Can I even do that or what happens when the web interface
is used to enter the network migration info, which is now not happening
on my nodes?

Jan
