Description Yi Zhao 2014-04-09 09:53:31 UTC 
Git rev: master/3e528d3e4bc542ca2f654c54363c56af0fb9f61b

Steps:
1. Set an invalid value for DISTRO in local.conf. e.g. DISTRO ?= "foo"
2. Run bitbake core-image-minimal

I got the following errors:
##########################
ERROR:  OE-core's config sanity checker detected a potential misconfiguration.
    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    Your version of bblayers.conf has the wrong LCONF_VERSION (has 6, expecting 5).
Please compare the your file against bblayers.conf.sample and merge any changes before continuing.
"meld conf/bblayers.conf /buildarea3/yzhao1/poky-build/meta*/conf/bblayers.conf.sample" is a good way to visualise the changes.
DISTRO 'foo' not found. Please set a valid DISTRO in your local.conf

ERROR: Execution of event handler 'check_sanity_eventhandler' failed
ERROR: Command execution failed: Exited with 1
############################

I didn't change the bblayers.conf or LCONF_VERSION. But the message showed there is a wrong LCONF_VERSION. Looks this message is redundant.
Comment 1 Paul Eggleton 2014-04-09 10:45:49 UTC 
I wouldn't describe it as redundant, just very annoying - this situation comes about because poky's LAYER_CONF_VERSION is out-of-step with OE-Core, and it's set in poky.conf so changing DISTRO means the value changes and then no longer matches the LCONF_VERSION in your bblayers.conf.

This is a long-standing problem, and I think we've reached the point where we really need to do something about it (for 1.7).

As Paul seems to have an idea about how to deal with this, assigning to him.
Comment 3 Paul Eggleton 2015-01-29 14:08:36 UTC 
I've sent out an RFC patch to the bitbake and OE-Core lists:

Comment 4 Paul Eggleton 2015-01-29 14:08:58 UTC 
Argh, wrong bug - ignore the previous message
Comment 5 Paul Eggleton 2015-02-05 12:07:09 UTC 
OK, I've just sent a couple of patches for this - one to the openembedded-core mailing list and one to the poky list (since both sides need fixing).
