The layer
"openembedded-core" does not start with "meta-".

  well, yes, but that's kind of a special case as it's the only
*required* layer. in any event, i apologize if i made a bigger deal
out of this than was warranted, i just thought the rules for layer
naming were a bit ambiguous and i wanted some clarification.

is it not a *requirement* that layers start with "meta-"?

[Robert P. J. Day]

  just proofing the BSP Guide and i read again that starting a layer
name with "meta-" is not an actual requirement, it's just standard
practice. but is there no code/script anywhere that requires that
prefix to process the layer properly?

  i'm pretty sure i've run across YP utilities that check specifically
for a "meta-" prefix, so that would make that prefix mandatory, would
it not? i wish i could remember where i've seen this, but it eludes me
at the moment.

If you use the yocto scripts for setting up a new layer, it
automatically prepends 'meta-'. That may be why there is no
requirement.Lachlan

  but that still doesn't address that (from memory) some OE
scripts/utils seem to *require* layers start with the prefix "meta-".
i guess i can just grep the OE layer and look for build scripts that
contain that string and see which ones have that requirement.

If anyone can locate some scripts or something that actually does require "meta-" to be prepended please let me know.  That changes how we describe this.

  as an admittedly simple example, i ran across this in oe-core's
scripts/contrib/documentation-audit.sh:

for pkg in `bitbake -s | awk '{ print \$1 }'`; do

	... snip ...

        if [[ "$pkg" =~ ^meta- || "$pkg" =~ ^packagegroup- || "$pkg" =~ -image ]]; then
                # Skip meta, task and image recipes
                continue
        fi


  checking that the package name starts with "meta-" seems to
pretty clearly suggest that it will be treated differently than if it
doesn't. i'm sure no one is terribly worried about that particular
script, but it does seem to show an example of this.

But that's checking *recipe* names, not layer names...

Thus, you'll have to look for another example. ;)

  ah, quite so, so perhaps the "meta-" prefix is not a real
requirement, just convention.
