[oe] persistent storage & RO rootfs

[André Draszik]

Hi,

I want to use a read-only rootfs, but some packages will need persistent
storage, which typically involves /var/lib/<package>

Two solutions come to mind:
- bbappend each involved recipe and set the --localstatedir ./configure
  option as needed
- symlink /var/lib/<package> to my persistent storage dir as needed

Anything else? What is typically done in such a case?


Cheers,
Andre'
