[yocto] packagegroup-core-boot failure for RTC-less system

[Jon Szymaniak]

Hi all,

I have a MACHINE_FEATURES which *does not* include "rtc", as the platform I
am working on doesn't have an RTC.

The busybox bbappend I'm using (attached below) uses the provided
defconfig, but
disables the HWCLOCK features.

However, my build is failing due to packagegroup-core-boot being unable to
meet the busybox-hwclock dependency. Looking at this line from
packagegroup-core-boot.bb, it seems to me that busybox-hwlock shouldn't be
getting placed in the core-boot's RDEPENDS, given that my MACHINE_FEATURES does
not include "rtc":

    ${@base_contains("MACHINE_FEATURES", "rtc", "busybox-hwclock", "", d)} \


Any thoughts or tips on debugging this? Perhaps there's somewhere I can stick a
print of MACHINE_FEATURES to verify that it is what I thought I set?


Thank you,
Jon
