pmbootstrap fails to install kernel to moto g5 plus; writing 'boot' \ (bootloader) Image size exceeded partition limits
Issue is as the title describes, this is a Moto G5 Plus running TWRP 3.3.1-0. Rootfs flashed with no issue, but it seems like the size allotted to the boot partition is too small? I'm not too familiar with the build process or kernels in general, but just a bit of direction here could help out a ton.
Thanks, here's the pmbootstrap log:

Ah, okay. It boots successfully from pmbootstrap flasher boot, but on the actual device there's no luck. Its strange because my device boot partition is 3347MB, but boot.img-motorola-potter seems to be only 28MB? Maybe that isn't the file you wanted me to check?

3.3 Gb sounds more like system partition, boot partition is usually much less than 100 Mb (sometimes less than 20 Mb on older devices)

Interesting, I'm not sure how I'd find that. I guess I'll look into slimming the boot.img then

No, flashing has never worked for the device so far, but I'm convinced the issue is related to the size of the boot.img. I looked around a bit more and found that other Moto devices have had similar issues in the past; the solution seems to be to enable a certain flag in the Kernel config, but I'm now having trouble figuring out how exactly to do that, and then how to check if I've properly built the kernel and initramfs?
Castellano says:
Enabling
CONFIG_KERNEL_LZMAnow the boot.img is 8MB and I can flash itI found this resource and ran
pmbootstrap kconfig edit motorola-potterI edited the flag CONFIG_RD_LZMA to 'y' and tried to flash after that with no success. I also removed the gzip as suggested, but there's no change.
Booting from pmbootstrap still works, however.
