> No,some MACHINEs not support qemu usermode
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)}
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.
