I will send a right one for the typos.
"Does this mean that MACHINEs which use qemu usermode won't be able to
use read-only images where this postinst cannot be executed on read-only
rootfs?"
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,
Jibin

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.
