When using different root directories with a wks file wic is using the value from the original ROOTFS_SIZE which is not correct. Example: Number Start End Size File system Name Flags 1 20.5kB 318MB 318MB fat16 otaefi legacy_boot, msftdata 2 318MB 636MB 318MB ext4 otaboot 3 636MB 1709MB 1074MB ext4 otaroot 4 1709MB 2027MB 318MB ext4 otaboot_b 5 2027MB 3101MB 1074MB ext4 otaroot_b 6 3101MB 5249MB 2147MB ext4 fluxdata The partitions 1, 2, and 3 incorrectly inherit the size, instead of using a computed size. With the patch applied it is working properly: Number Start End Size File system Name Flags 1 20.5kB 14.5MB 14.5MB fat16 otaefi legacy_boot, msftdata 2 14.5MB 65.3MB 50.8MB ext4 otaboot 3 65.3MB 1139MB 1074MB ext4 otaroot 4 1139MB 1190MB 50.8MB ext4 otaboot_b 5 1190MB 2264MB 1074MB ext4 otaroot_b 6 2264MB 4411MB 2147MB ext4 fluxdata As for the removal of the bb.warn, if the size is not specified, it is not something to warn the end user about. Some of my default images make use of the head room + a computed directory size or while generating images.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
