[Thinstation-developer] modify pkg to add wget and scp source

[Greg <ml...@re...>]

Hello All,

I've deploy some workstations that connect to the thinstation "master" 
over a NAT network.
pkg only supports tftp source but tftp don't work over NAT.

I think it could be interesting to re-use "transport" function presents 
into packages/base/etc/init.d/network_files
So I migrate transport function from network_files to 
thinstation.functions to permit a usage with pkg.

During the migration I've remark that wget don't follow $cpath unlike 
tftp and scp.
So I've modify "wget -P /tmp" to "wget -O $cpath". This correction also 
allow to use transport for pkg.

Please found a patch that remove transport from network_files and add it 
to thinstation.functions. It also modify pkg to use transport function.


Best regards,
Grégory
