That's not what I was asking.
You're disabling whole build-time postinst when qemu-usermode is in
MACHINE_FEATURES with:
${@bb.utils.contains('MACHINE_FEATURES', 'qemu-usermode',
'true','false', d)}
Hi,
It seems that the built-time postinst will be disable when qemu-usermode
is *not* in MACHINE_FEATURES.
If anywhere wrong, please correct me.
Thanks.
and in that case read-only images will fail to build and even if you
remove that error (failed postinst scripts are causing errors when the
image is configured to be read-only), then the image is still bad for
runtime, because with read-only rootfs you cannot generate fontcache
even on the device.

"Does this mean that MACHINEs which use qemu usermode won't be

No,some MACHINEs not support qemu usermode, when used, it will
lead to a qemu core dump: "qemu: uncaught target signal 11
(Segmentation fault) - core dumped".
so when use qemu usermode,check whether the machine supports it
first.
Thanks,

fontcache uses quemu usermode by default, but some architecture
such as Intel skylake does not support qemu usermode, this can
lead to a build warning as below:
"WARNING: The postinstall intercept hook 'update_font_cache'
failed".
Add a judgement of qemu usermode to fix the build warning.
