OpenWrt has an automated build machine that creates a binary on-the-fly, pulling in a list of requested packages. The package selection isn't necessarily interesting for your study, but the variation of manufacturer/models could be.

You can see the stats at: https://sysupgrade.openwrt.org/stats

There are all kinds of things "wrong" with this data:

- It's not used (yet) by the general OpenWrt community

- This server use is skewed toward developers

- Those people may have more powerful machines

- What the heck is going on with the Linksys_e8450?

But maybe it's a useful quick-look at various semi-popular models. You can look up device specs in the OpenWrt Table of Hardware: https://openwrt.org/toh/start

Have fun!
