[yocto] Offline use of opkg

[Sebastian Rohde]

Hello everybody,

in my setup opkg is used as the package manager and I use it to install 
/ uninstall several software alternatives. I want this to work on 
deployed devices in an offline fashion, i.e. I want to do "opkg install 
<sompackage>" without internet access. <somepackage> might or might not 
be installed in the actual rootfs in the original image.

I could really use some hints how this could be achieved without running 
into a dead end. My current idea is to deploy the ipks somehow into the 
rootfs und point opkg to the "local repository":

1. Make some kind of meta-recipe with a dependency of the do_install 
task on <somepackage>'s do_write_ipk task
2. Find somehow the filenames of all ipks generated by a selection of 
recipes (the ones creating <somepackage>)
3. Install them to the rootfs, generate Packages.gz
4. Point opkg to this local repository

For steps 1 and 2, I am not sure whether that is possible with a 
reasonable effort and I would be very thankful for any guidance.

Regards

Sebastian
