Subject sez it all, boot qemu with serial and you will see this error every time!

Also seen on Freescale ARM-based boards when building core-image-minimal, but I suspect I would see it on other image builds as well.

Hi Saul,

This error is caused by the changes introduced by the following commit.

commit db5847dd411f12b8b96b9bee624e9be30b504653

    initscripts: let populate-volatile.sh create the /tmp link
    
    Previously, the /tmp link (/tmp -> /var/tmp) was created by the
    bootmisc.sh script. So in case of a read-only rootfs, this symlink
    would not be created correctly.
    
    The populate-volatile.sh script is intended to handle all directories
    and files related to volatile storage, so we should let it create
    the /tmp link.
    
    In addition, because of the improments of populate-volatile.sh, the data
    loss problem of bug#3404 is also resolved by this patch.

And it will be gone if the populate-volatile.sh related patches are merged.

For now, the populate-volatile.sh script doesn't handle link config items correctly, so if the target (in this case, /tmp) has already existed, the script will just skip this item, thus resulting /tmp->/var/tmp link not created.
