Recently Debian-style support for link relocation was added to
'update-alternatives' script, but it fails under circumstances where
host rootfs root directory differs from target rootfs root directory
and two alternative packages provide a symbolic link with source
located in different directories.
An example of the case is busybox provided /bin/rev (symlinking to
/bin/busybox.nosuid) and util-linux provided /usr/bin/rev (symlinking
to /usr/bin/rev.util-linux) in which case following failure occurs
during image recipe's do_rootfs() task:
ERROR: core-image-minimal-1.0-r0 do_rootfs: Postinstall scriptlets of ['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 .../tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/temp/log.do_rootfs.
ERROR: core-image-minimal-1.0-r0 do_rootfs: Function failed: do_rootfs
Looking in log.do_rootfs file, following relevant lines can be observed:
update-alternatives: renaming rev link from /bin/rev to /usr/bin/rev
mv: cannot stat '/bin/rev': No such file or directory
Mitigate issue by applying patch which adds target root filesystem root
directory path prefix to failing 'mv' calls relevant variable references

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.
