# Rebuild and install initramfs for the specified dist-kernel.
# <kv-dir> is the kernel source directory (${KV_DIR} from linux-info),
# while <kv-full> is the full kernel version (${KV_FULL}).
# The function will determine whether <kernel-dir> is actually

#
# <kv-dir> -- the full path to the target kernel (default: ${KV_DIR})
#
# <kv-full> -- the target kernel version (default: ${KV_FULL})
#
# <installkernel-args> -- extra optional arguments for installkernel
# see man kernel-install and man installkernel. Requires at
# least version 56 of sys-kernel/installkernel.
#
# This function is to be used in pkg_postinst() of ebuilds installing
# kernel modules that are included in the initramfs.
# kernel modules that are included in the initramfs. In order to
# reinstall *all* distribution kernels currently installed on the
# system add the --all argument (requires installkernel-56 or newer).
