I'm having some trouble with it...

If I want to use .bbappend do I need to add bblayers as well?

If I don't I get this error message:

    ERROR: /home/jdj/oe/mystuff/recipes/netbase/netbase_4.21.bbappend is
    not a BitBake file while parsing
    /home/jdj/oe/mystuff/recipes/netbase/netbase_4.21.bbappend


Where /home/jdj/oe/mystuff/recipes/netbase/netbase_4.21.bbappend is:

    FILESEXTRAPATHS := "${THISDIR}/${PN}-${PV}"
    PRINC = "1"


If I do use bblayers, I'm not sure about my local.conf. It contains some

    BBFILES, BBFILE_COLLECTIONS, BBFILE_PATTERN_xxx and
    BBFILE_PRIORITY_xxx lines

If I remove these lines then it looks like bitbake can't find any recipe.
