Probably something worth reporting upstream to dracut maintainers then.
I'll do this next time I speak to Harald, but if you would like to fix
it it's probably quite trivial.

You've maybe not played with very many very minimal systems as I've come
across this kind of thing quire frequently. Having played about in
dracut shells rather a lot of late I have to admit it's a total pain.
I'll see what can be done to make this a bit more friendly.

</I>
If such helper scripts exist and are useful, we can easily add them to a
dracut.conf.d snippet. These config snippets can be included in the
packages that provide these helpers rather than in dracut itself to
allow for proper separation of need (although the complex dependancies
may mean that we do not want to include e.g. the xfs helper (which may
or may not pull in a lot of other tools) if you do not have any xfs
filesystems - in which case it has to be patched into the various dracut
modules instead of done generically.
That said, as with your other point above, anything added to the initrd
will make it bigger and thus delay the boot. So you have to strike a
happy balance with having enough to be useful in a (rare) emergency case
and small enough to be spritely during the (more frequent rebooting
process).
