[yocto] Where should I append Yocto bitbake task to create work folder symlink ?

[Woronicz, Bartosz ( NSN - PL/Wroclaw)]

The problem is, it doesn't doit delirebately,

when I run

bitbake -f -c latest_link myrecipe , it works

when the process is in the tasks batch running
bitbake myrecipe
it doesn't
What am I doing wrong ?

Kind regards,
