[yocto] [meta-oe] build error using read-only-rootfs with samba

[Johannes Pointner]

Hello,

I recently upgraded to fido and tried to build core-image-x11 but I
get the following error if I include the samba package:

Collected errors:
* extract_archive: Cannot create symlink from ./var/log to
'volatile/log': File exists.

I think I was able to find the cause of the problem, it seems that
samba package is trying to install /var/volatile/log/samba as well as
samba-base package by using the volatile script.

But I'm not sure, why the samba package is creating /var/volatile/log/samba.

Thx,
Hannes
