from https://dracut.wiki.kernel.org/index.php/Main_Page :

  * Scripts that end up on the initrd should be POSIX compliant. dracut
    will try to use /bin/dash as /bin/sh for the initrd if it is
    available, so you should install it on your system -- dash aims for
    strict POSIX compliance to the extent possible.
  * Hooks MUST be POSIX compliant -- they are sourced by the init
    script, and having a bashism break your user's ability to boot
    really sucks.

Seems like having dracut depending on bash may not be a good idea.

Or is there a way to make sure dracut scripts & hooks will use bash in 
POSIX-compliant mode ?
