(asked about this on the OE list recently, but no response, so i'll
harass this list.)
poking around initramfs content and recipes, and noticed this in the
latest poky checkout:
$ grep -rw INITRD_IMAGE *
documentation/ref-manual/ref-variables.xml: <glossentry
id='var-INITRD_IMAGE'><glossterm>INITRD_IMAGE</glossterm>
documentation/ref-manual/ref-variables.xml: INITRD_IMAGE[doc] =
"When building a "live" bootable image (i.e. when IMAGE_FSTYPES contains
"live"), INITRD_IMAGE specifies the image recipe that should be built to
provide the initial RAM disk image."
documentation/ref-manual/ref-variables.xml: contains
"live"), <filename>INITRD_IMAGE</filename>
meta/recipes-extended/images/core-image-testmaster.bb:INITRD_IMAGE =
"core-image-testmaster-initramfs"
$
so ... a bit of documentation on the alleged variable INITRD_IMAGE,
and a single assignment, and no usage.
but if i drop the requirement that it be a word:
$ grep -r INITRD_IMAGE *
documentation/ref-manual/ref-variables.xml: <glossentry
id='var-INITRD_IMAGE'><glossterm>INITRD_IMAGE</glossterm>
documentation/ref-manual/ref-variables.xml: INITRD_IMAGE[doc] =
"When building a "live" bootable image (i.e. when IMAGE_FSTYPES contains
"live"), INITRD_IMAGE specifies the image recipe that should be built to
provide the initial RAM disk image."
documentation/ref-manual/ref-variables.xml: contains
"live"), <filename>INITRD_IMAGE</filename>
meta/recipes-extended/images/core-image-testmaster.bb:INITRD_IMAGE =
"core-image-testmaster-initramfs"
meta/classes/image-vm.bbclass:# Using an initramfs is optional. Enable it by
setting INITRD_IMAGE_VM.
meta/classes/image-vm.bbclass:INITRD_IMAGE_VM ?= ""
meta/classes/image-vm.bbclass:INITRD_VM ?=
"${@'${DEPLOY_DIR_IMAGE}/${INITRD_IMAGE_VM}-${MACHINE}.cpio.gz' if
'${INITRD_IMAGE_VM}' else ''}"
meta/classes/image-vm.bbclass:do_bootdirectdisk[depends] +=
"${@'${INITRD_IMAGE_VM}:do_image_complete' if '${INITRD_IMAGE_VM}' else ''}"
meta/classes/image-live.bbclass:INITRD_IMAGE_LIVE ?=
"core-image-minimal-initramfs"
meta/classes/image-live.bbclass:INITRD_LIVE ?=
"${DEPLOY_DIR_IMAGE}/${INITRD_IMAGE_LIVE}-${MACHINE}.cpio.gz"
meta/classes/image-live.bbclass: initrd_i = d.getVar('INITRD_IMAGE_LIVE',
True)
meta/classes/image-live.bbclass: bb.error('INITRD_IMAGE_LIVE %s cannot
use image live, hddimg or iso.' % initrd_i)
$
suddenly, i see references to "INITRD_IMAGE_VM" and
"INITRD_IMAGE_LIVE". so is "INITRD_IMAGE" correct? i don't see how
that makes sense unless "VM" and "LIVE" are some weird form of
override.
thoughts?
