If you have dash installed dracut will use it instead of bash. It is *that* simple.
But, I'm not much concerned here about POSIX compliance as I'm concerned about it
actually being a good replacemente to mkinitcpio *and* actually booting the machines
of users.

I based my package on fedora's. So, the dependencies were carefully replicated to avoid
issues. But anyone can hack it later to use dash or busybox.
