Actually, thinking about it I don't think this is expected to work. Typically,
recipes that need a specific user to exist use useradd.bbclass themselves
rather than depending upon another recipe that does it. However, if you do
need to do it in a separate recipe (e.g. because multiple recipes use the same
user account), just adding the other recipe to DEPENDS does not guarantee that
it will be around at runtime - the actual package generated by the other
recipe (usually the same name) would need to be added to RDEPENDS_${PN}.
Additionally, if you do this, you should be able to have your postinstall
script run at all times; it should not need to be guarded to run only on the
target (although https://bugzilla.yoctoproject.org/show_bug.cgi?id=5318 may
interfere with this if you are using ipk or deb.)
Cheers,
Paul
