Hi Mike,

Could you send your tailscale recipe to meta-openembedded/meta-networking?
 =C2=A0=C2=A0=C2=A0 Email: OpenEmbedded Development mailing list=20
<openembedded-devel@lists.openembedded.org>
 =C2=A0=C2=A0=C2=A0 Instructions:=20
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded

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