# The rpm-utils and rpm-utils-initramfs targets are identical except for the
# zfs-initramfs package: rpm-utils never includes it, rpm-utils-initramfs
# includes it if detected at configure time. The zfs-initramfs package does
# not work on any known RPM-based distribution and the resulting RPM is only
# used to create a Debian package. The rpm-utils-initramfs target is not
# intended to be specified by the user directly, it is provided as a
# dependency of the deb-utils target.
