I encountered a build issue when trying to generate /etc/inittab.
I have a meta-xxx/conf/machine/conf file which contains serial console information such as
SERIAL_CONSOLE = "115200 ttyXYZ" or "115200 ttyS0" by default.
When I update that conf file and make an incremental build, the /etc/inittab
doesn't get updated, I finally have to remove all the binaries and force a
complete re-build to generate correct /etc/inittab with updated serial console
settings, which take more than an hour to finish.
How do I create a dependency so that when I update my machine/conf file, an
incremental build would take care of the change and re-generate the files in
root FS accordingly? If that is impossible for now, can I just delete one or a
few task binaries to trigger a rebuild on /etc/inittab? This would greatly
reduce my build time.
You really only need to rebuild the sysvinit package.
% ... make your modifications to machine/conf
% bitbake sysvinit -c cleansstate
% bitbake <whatever-image-you-like>
This package is not marked as machine dependent via
PACKAGE_ARCH = "${MACHINE_ARCH}"
perhaps it should be since /etc/inittab is target dependent?
