thanks for the quick reply I tried your suggestion but I get:

Did you include the bbclass?

I think in this case the INHERIT doesn't work !
Well I have in distro config:

require classes/distroversion.bbclass

which has a single python function

def get_distro_version(d, dirty=True, abbrev=None):

which basically calls "git describe --always --dirty --abbrev=8",
the last one was added when git versions started behaving differently
and breaking reproducibility.

And then distro config also has:

DISTRO_VERSION := "${@get_distro_version(d)}"

This works for me up to yocto 3.1 dunfell at least.
