From da3dacfa5e63ca00d4c8efd8c3c603bce7937cdd Mon Sep 17 00:00:00 2001
From: Harald Hoyer <harald@redhat.com>
Date: Thu, 6 Feb 2014 16:45:20 +0100
Subject: [PATCH] Factor out all the "type -V" commands
Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
(cherry picked from commit 30e6e809ed8d189cc8374df3c28cfbcab5a299b9)
