# 99-finish in base depends on some other module which mounts
# the rootfs, like 90-rootfs. To replace that default, use
# BAD_RECOMMENDATIONS += "initramfs-module-rootfs" in your
# initramfs recipe and install something else, or install
# something that runs earlier (for example, a 89-my-rootfs)
# and mounts the rootfs. Then 90-rootfs will proceed immediately.
