I needed the other way around: being able to overlay nfs-mounted shares...

Me too.

CentOS 7 read-only configuration via NFSv3.
Being able to overlay it with a read-writable tmpfs (or the like) would be what I am searching for.
Is this possible?

This has been possible for a long time with AUFS already. AUFS with nfs support is in ubuntu, not sure about centos.

I am using it for embedded development: One layer contains the base rootfs as built by our CI, one layer contains my own modifications, one layer contains anything written by the test device.

The root of the layered mount is exported via nfsroot, you just make sure you are mounting with the ",v=3" option

Thanks, that sounds promising.

However, we're bound to RHEL/CentOS 7.
Will check.
