This has been fixed in upstream of OE-Core and in newer versions
of Yocto. For Edison provide our own version of the pkg_postinst
and pkg_postrm routines. It is not clear yet if this conflicts with
newer versions of poky but all that could happen is that the symlink
is changed twice and removed twice but the command ends with a || true
so this should not cause any kind of fault.
* Enable verbose detection, add CP2012 based serial adapter support
* Only enable USB1.1 HCD for now to fix the detection of the USB serial
adapters
* Enable more filesystems in the config to allow upgrading the boot
partition during the runtime (after installing the right codepage)
