Re: [yocto] recipe to clean up files from rootfs

[Chris Simmonds]

Hi Sherif,

Maybe this is a little late, but as been said already, the best solution
is to remove psplash from your image altogether. You can to this quite
simply by adding to your conf/local.conf

IMAGE_FEATURES_remove = "splash"




Rationale: the dependency on the psplash program is (usually) set in the
image recipe. For example, in
meta/recipes-core/images/core-image-base.bb, you see

IMAGE_FEATURES += "splash"

The image class (meta/classes/image.bbclass) matches the list of
features in IMAGE_FEATURES with package names in FEATURE_PACKAGES_*. So,
in meta/classes/image.bbclass, you find

SPLASH ?= "psplash"
FEATURE_PACKAGES_splash = "${SPLASH}"

This causes "psplash" to be added to the image if IMAGE_FEATURES
contains the string "splash".

By using IMAGE_FEATURES_remove, you remove the string "splash" from the
list of features and so psplash will not be included in your image.

HTH,
Chris Simmonds.

I think you are fundamentally misunderstanding how recipes work. At a
very high level, recipes are used to compile sources into installable
packages (e.g. ipk or rpm files) and then (as a separate step) an
image recipe creates the rootfs by unpacking a set of installable
packages.

One recipe can depend on the output of another (e.g. an image recipe
depends on the installable packages created by other recipes) but each
recipe has it's own execution environment. You can't expect to write a
recipe which changes the behaviour of another recipe, so writing a new
recipe to remove some files from the rootfs created by the image
recipe is fundamentally wrong. It's never going to work, even if you
fix every typo.

As suggested already, the normal and recommended way to remove files
from the rootfs is:

  1) Remove the package which provides the file(s) from the image you
are building (ie don't install the files in the rootfs at all).

If the file(s) you want to remove don't match the granularity of the
installable packages (ie you want to keep some files provided by a
package but remove others) then you have two basic options:

  2) Spilt the installable package into multiple smaller installable
packages (ie modify the packaging rules in the recipe which creates
the installable package).

  3) Postprocess the rootfs. For that to work, you need to add the
postprocessing function ** TO THE IMAGE RECIPE **.

${D} won't work here, grep on ROOTFS_POSTPROCESS_COMMAND for recipes that get 
it right.


And, much much much better would be to just not install psplash into your image!

     You can use ROOTFS_POSTPROCESS_COMMAND in your image recipe to do
some

Re: [yocto] recipe to clean up files from rootfs

[Sherif Omran]

here is my recipe, the aim was to remove some files from the init.d folder
and tweek before creating the image

#
# This file was derived from the 'Hello World!' example recipe in the
# Yocto Project Development Manual.
#

SUMMARY = "This recipe removes any missing files from the filesystem before
finalinzing it"
SECTION = "base"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

#SRC_URI = "file://*"

S = "${WORKDIR}"
BB_STRICT_CHECKSUM ="0"
ALLOW_EMPTY_${PN}="1"


#IMAGE_INSTALL = "packagegroup-core-boot packagegroup-base-extended
${CORE_IMAGE_EXTRA_INSTALL}"
#IMAGE_INSTALL = "${CORE_IMAGE}"

#inherit core-image

my_postprocess_function() {
 rm -r ${D}${bindir}/init.d/psplash.sh
}

ROOTFS_POSTPROCESS_COMMAND += "my_postprocess_function; "

Re: [yocto] recipe to clean up files from rootfs

[Mike Looijmans]

Well, start by sharing yours first.

Be careful when naming your shell routine, sometimes OE considers parts behind 
the underscore as overrides and then it cannot find it.

You can use ROOTFS_POSTPROCESS_COMMAND in your image recipe to do some
last-minute filesystem cleanup.

However, in most cases it's much better to determine what recipe puts the
files there and modify the recipe or remove the package. It would help a
lot if you would reveal what files you want to remove and why.

Have a look at ROOTFS_POSTPROCESS_COMMAND.
