Hi Thomas,

If the machine layer definition is applied after meta-systemd also

1) Where in meta-systemd is SERIAL_CONSOLE being set? I can't find it
anywhere in there.
It's actually in OE-core:
meta/recipes-core/systemd/systemd-serialgetty.bb
3) When the machine configuration sets the value, that happens pretty
early on in the parsing process so there's no way that this value is
going to take precedence over the machine value. Have you looked at the
output of bitbake -e systemd-serialgetty | less to see how the value of
this variable is being set?
Right, then my comment stands. Setting the value with ?= in systemd-
serialgetty.bb is not going to override a value set by the machine
configuration, whether the machine configuration uses ?= or = - the machine
configuration is parsed first, and ?= means "set if not already set" - which it
will be by the time the recipe is parsed.
I still think it's wrong to be setting such a variable in
this [obscure] recipe.
