Hi,
I'm facing a problem by trying to shrink the size of our root filesystem.
To avoid installing some unneeded tools such as adduser, groupadd,
nologin, etc. I just created as usual a shadow_%.bbappend in our layer
which removes the content using do_install_append:
# do not install alternatives
ALTERNATIVE_${PN} = ""
ALTERNATIVE_${PN}-base = ""
# remove unwanted files on target
do_install_append_class-target () {
rm -r ${D}${base_bindir}
rm -r ${D}${base_sbindir}
rm -r ${D}${bindir}
rm -r ${D}${sbindir}
}
Building an image with this works well and I got rid of the unwanted
tools but I get an error whenever I try to build the SDK for this image
with do_populate_sdk:
WARNING: ceres-image-1.0-r0 do_populate_sdk:
nativesdk-util-linux.postinst returned 1, marking as unpacked only,
configuration required on target.
ERROR: ceres-image-1.0-r0 do_populate_sdk: Postinstall scriptlets
of ['nativesdk-util-linux'] have failed. If the intention is to defer
them to first boot,
then please place them into pkg_postinst_ontarget_${PN} ().
Deferring to first boot via 'exit 1' is no longer supported.
Details of the failure are in
/home/chsingj/yocto-thud/tmp/work/ceres_con-oe-linux-gnueabi/ceres-image/1.0-r0/temp/log.do_populate_sdk.

The log file shows an error with update-alternatives (probably a
failing ln call):
update-alternatives: Error: not linking

exists and is not a link
If I remove the bbappend, the SDK builds fine but of course my image
contains the unwanted files. I tried many other recipe tweaks but I
can't get over some build errors. I'd like to avoid a solution using
ROOTFS_POSTPROCESS_COMMAND in the image recipe as I would have to
explicitely list all shadow tools and it would blow up my recipe. Is
there any solution here? Is it maybe a bug that can be fixed? Thanks!
Regards,
Jeremy
