Public bug reported:
When one uses UEFI boot and /boot/efi runs out of space, executing
sudo update-initramfs -u -k all
will silently fail even though the output looks like everything went
okay. The generated initrd files may be missing the end of the file and
boot obviously fails as a result!
To reproduce, try filling the EFI partition to less than 10 MB free and
then install a new kernel using apt and try to boot to it. The initrd
file would need more than 10 MB disk space but you'll get no errors
about the problem and the boot simply fails.
