i2cget, i2cset, i2cdump and i2cdetect may also be provided by Busybox
when CONFIG_I2CGET, CONFIG_I2CSET, CONFIG_I2CDUMP and CONFIG_I2CDETECT
are enabled respectively.
Busybox has a priority of 50.
Prior to the patch building core-image-minimal with
IMAGE_INSTALL_append = " busybox"
IMAGE_INSTALL_append = " i2c-tools"
in local.conf produced the warnings
WARNING: core-image-minimal-1.0-r0 do_rootfs: busybox.postinst returned 1, marking as unpacked only, configuration required on target.
WARNING: core-image-minimal-1.0-r0 do_rootfs: Intentionally failing postinstall scriptlets of ['busybox'] to defer them to first boot is deprecated. Please place them into pkg_postinst_ontarget_${PN} ().
If deferring to first boot wasn't the intent, then scriptlet failure may mean an issue in the recipe, or a regression elsewhere.
Details of the failure are in /path/to/poky/build/tmp-glibc/work/qemux86-oe-linux/core-image-minimal/1.0-r0/temp/log.do_rootfs.
WARNING: core-image-minimal-1.0-r0 do_rootfs: [log_check] core-image-minimal: found 1 warning message in the logfile:

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
