# After a kernel transaction, verify the ESP actually received the new kernel
# and repair it if it did not.
#
# This is auto-recovery rather than a warning: if mkinitcpio's own hook was
# skipped (the ParallelDownloads segfault bug), this puts the kernel and
# initramfs on the ESP before the machine is ever rebooted. If it cannot, it
# exits non-zero so the transaction ends loudly instead of silently succeeding.
#
# Note: this hook is itself forked by alpm, so it is subject to the same
# segfault bug it compensates for. That is why boot-repair also enforces
# ParallelDownloads = 1 — belt and braces.
