Description Ross Burton 2020-10-15 07:01:47 UTC 
I want to add a RDEPENDS to dropbear from a machine configuration:

RDEPENDS_dropbear_append_pn-dropbear = " ssh-pregen-hostkeys"

This gives a warning that RDEPENDS_dropbear is conflicting with RDEPENDS_${PN} in the dropbear recipe. Okay, I'll change that to ${PN}:

RDEPENDS_${PN}_append_pn-dropbear = " ssh-pregen-hostkeys"

Comment 1 Richard Purdie 2021-08-02 15:43:31 UTC 
Investigation shows this is a data store bug. Note that in RDEPENDS_${PN} (), the "()" is always empty. None values were being corrupted to "" for inactive overrides.

I've send a patch to fix datastore behaviour and added a test.
