New issue by g4s8 on void-packages repository

https://github.com/void-linux/void-packages/issues/42047

Description:
The problem: I updated kernel version, it successfully generated initramfs using drakut and copied kernel vmlinuz file to boot partition but failed to copy initramfs due to "No space left on device" error. Then xbps continued to execute configuration hooks and generated new grub config. Grub has found vmlinux file for new kernel, so it generated new entry for this version. But during boot initramfs was not found, so boot failed with kernel panic.

I'm suggesting to stop configuration execution if any hook fails and skip other hooks to avoid it.

xbps log:
