  I don't use wireguard myself, but if a package includes a kernel
driver you have to be really careful that you keep them in sync.  I run
into this possibility with video drivers (nvidia, radion, etc) all the time.

  ... and that is the reason that I do horrible things to my RPIs and
their storage like compiling the kernel and poudriere my packages.  :D
