I dare say that if you are concerned about safety of the bootup process,
you should consider yaird as alternative to initramfs-tools to generate
your ramdisks.
The above would not happen with yaird: The generated ramdisk would be
hardcoded to using RAID to reach your root filesystem.
Initramfs-tools is flexible and _mostly_ does as expected. Which is
great for some situations (like moving harddisk to different hardware)
but not all (like running a server as stable as possible).
