I've added Yann E. Morin in Cc. He is working on a revamp of the root
filesystem skeleton for the systemd case, specifically to solve this
sort of problem.

You can have a look at
https://github.com/yann-morin-1998/buildroot/commits/yem/systemd-skeleton,
but I'm not sure it's the latest updated work from Yann.

Best regards,

Thomas
