Here is the whole bbclass:

DESCRIPTION = "Creates symlink to the latest version workdir of the package"

do_latest_link() {
    if [ -n "${WORKDIR}" ]; then
        linkname="$(dirname ${WORKDIR})/latest"
        rm -f $linkname
        ln -s $(basename ${WORKDIR}) $linkname
    fi
}
addtask latest_link after do_unpack

do_unpack[postfuncs] += "do_latest_link"

But for better understanding I made the more throughout look into the documentations. I found the information about "postfuncs" you talk about [1]. However, the tasks description [2] doesn't say anything about including the task in the process, it just describes the demanded order that the task is put ( addtask something after|before othertask ).

That is so, until I read "3.6. Variable Flags"  [3]. Where is quite clearly stated those variables control functionality and *dependencies*.
The documentation is quite unclear in that case.

If you're using a postfunc you don't need to addtask at all: using postfuncs means you don't need to have a separate task at all.
