The dracut/02zfsexpandknowledge/module-setup.sh.in has a syntax error
which makes the script unusable by a POSIX compliant shell like Dash
on Debian based systems.

When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.
Important note: this code will not accomplish its stated goal until this
bug is fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1385432
That bug impacts more than just ZFS. It impacts LUKS, dmraid, and
unmount during poweroff. It is a Fedora-wide bug.

The behavior of the Dracut module was very wrong before.
The correct behavior: initramfs should not run `zfs-mount` to completion
if the two generator files exist. If, however, one of them is missing,
it indicates one of three cases:
* The kernel command line did not specify a root ZFS file system, and
another Dracut module is already handling root mount (via systemd).
`mount-zfs` can run, but it will do nothing.
* There is no systemd to run `sysroot.mount` to begin with.
`mount-zfs` must run.
* The root parameter is zfs:AUTO, which cannot be run in sysroot.mount.
`mount-zfs` must run.
In any of these three cases, it is safe to run `zfs-mount` to completion.
`zfs-mount` must also delete itself if it determines it should not run,
or else Dracut will do the insane thing of running it over and over again.
Literally, the definition of insanity, doing the same thing that did not
work before, expecting different results. Doing that may have had a great
result before, when we had a race between devices appearing and pools
being mounted, and `mount-zfs` was tasked with the full responsibility
of importing the needed pool, but nowadays it is wrong behavior and
should be suppressed.
I deduced that self-deletion was the correct thing to do by looking at
other Dracut code, because (as we all are very fully aware of) Dracut
is entirely, ahem, "implementation-defined".

Based upon @ryao's initial fix for 1c73494394fc9de9283b3fd4f00bcdf4bd300a7
( 5e9843405f63fdabe76e87b92b81a127d488abc7 ) this one also uses
`command -v` instead of `type`, but additionally only applies the
fix to close zfsonlinux/zfs#4749 when `libgcc_s.so.1` has not been included
by dracut automatically (verified by whether `zpool` links directly to
`libgcc_s.so`), as well as change the fallback option to match `libgcc_s.so*`.

- In older systems without sysroot.mount, import before dracut-mount,
and re-enable old dracut mount hook
- rootflags MUST be present even if the administrator neglected to
specify it explicitly
- Check that mount.zfs exists in sbindir
- Remove awk and head as (now unused) requirements, add grep, and
install the right mount.zfs
- Eliminate one use of grep in Dracut
- Use a more accurate grepping statement to identify zfsutil in rootflags
- Ensure that pooldev is nonempty
- Properly handle /dev/sd* devices and more
- Use new -P to get list of zpool devices
- Bail out of the generator when zfs:AUTO is on the root command line
- Ignore errors from systemctl trying to load sysroot.mount, we only
care about the output
- Determine which one is the correct initqueuedir at run time.
- Add a compatibility getargbool for our detection / setup script.
- Update dracut .gitignore files

Dracut and Systemd updated how they integrate with each other, because
of this our current integrations stopped working (around the time
4.1.13 came out). This patch addresses that issue and gets us booting
again.

letting me submit this on his behalf.

Build products from an out of tree build should be written
relative to the build directory. Sources should be referred
to by their locations in the source directory.
This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile. This enables the following:
$ mkdir build
$ cd build
$ ../configure \
--with-spl=$HOME/src/git/spl/ \
--with-spl-obj=$HOME/src/git/spl/build
$ make -s
This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.
Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
Makefile.am:00: but option 'subdir-objects' is disabled
