Hi Mike,

Could you send your tailscale recipe to meta-openembedded/meta-networking?
     Email: OpenEmbedded Development mailing list 
<openembedded-devel@lists.openembedded.org>
     Instructions: 
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded

It looks like all the work is done aside from an email!
