This is with 'daisy'.

Ah - that shows:

# $SRC_URI [8 operations]
#   set /media/SSD-RAID/poky-git/meta/conf/bitbake.conf:588
#     ""
#   set /media/SSD-RAID/poky-git/meta/conf/documentation.conf:378
#     [doc] "The list of source files - local or remote. This variable tells the OpenEmbedded build system what bits to pull in for the build and how to pull them in."
#   set /media/SSD-RAID/poky-git/meta/recipes-kernel/linux/linux-yocto_3.10.bb:23
#     "git://git.yoctoproject.org/linux-yocto-3.10.git;bareclone=1;branch=${KBRANCH},${KMETA};name=machine,meta"
#   append /media/SSD-RAID/meta-keylevel-sjs/project-specific-layers/opty4-valleyisland/recipes-kernel/linux/linux-yocto_3.10.bbappend:4
#     " file://enable-R8169.cfg"
#   append /media/SSD-RAID/meta-keylevel-sjs/project-specific-layers/opty4-valleyisland/recipes-kernel/linux/linux-yocto_3.10.bbappend:5
#     "file://fsdfsdfdsfsd"
#   finalize ast.py:323 [finalize]
#     "was: git://git.yoctoproject.org/linux-yocto-3.10.git;bareclone=1;branch=${KBRANCH},${KMETA};name=machine,meta  file://enable-R8169.cfg file://fsdfsdfdsfsd"
#   override[valleyisland-64]:set /media/SSD-RAID/meta-intel-git-2/meta-isg/meta-valleyisland/recipes-kernel/linux/linux-yocto_3.10.bbappend:33

#   finalize override[valleyisland-64]:
#     "git://git.yoctoproject.org/linux-yocto-3.10.git;protocol=git;nocheckout=1;branch=${KBRANCH},${KMETA},valleyisland-io-3.0;name=machine,meta,valleyisland-io"

SRC_URI="git://git.yoctoproject.org/linux-yocto-3.10.git;protocol=git;nocheckout=1;branch=standard/base,meta,valleyisland-io-3.0;name=machine,meta,valleyisland-io"

If I change my bbappend to use lines of the form:

  SRC_URI_valleyisland-64 += " file://enable-R8169.cfg"

then the fragments make it in to the configuration.

I've never really understood machine overrides that well - I thought that using a plain SRC_URI would apply regardless, but that's obviously not the case ;-)

Thanks for the pointer :-)
