наб 0864c29e7c contrib; dracut: centralise root= parsing, actually support root=s
So far, everything parsed root= manually, which meant that while
zfs-parse.sh was updated, and supposedly supported + -> ' ' conversion,
it meant nothing

Instead, centralise parsing, and allow:
  root=
  root=zfs
  root=zfs:
  root=zfs:AUTO

  root=ZFS=data/set
  root=zfs:data/set
  root=zfs:ZFS=data/set (as a side-effect; allowed but undocumented)

  rootfstype=zfs AND root=data/set <=> root=data/set
  rootfstype=zfs AND root=         <=> root=zfs:AUTO

So rootfstype=zfs /also/ behaves as expected, and + decoding works

It was added in the original ae26d0465a ("Add dracut support") commit

plymouth --command splits the command on spaces which means
that zfs-load-key was getting the filesystem name enclosed
in single quotes (since 13c59bb76) and failing. This commit
fixes it by piping the password directly to the command
similar to how it's done in other scripts (initramfs,
dracut without plymouth).

dracut: use /bin/sh instead of bash as the intepreter
Despite that dracut has a hard dependency on bash,
its modules doesn't, dracut only has a hard dependency on bash for
module-setup (on a fully usable machine). Inside initramfs, dracut
allows users choose from a list of handful other shells, e.g. bash,
busybox, dash, mkfsh.

In fact, my local machine's initramfs is being built with dash,
and it's functional for a very long time.

Before 64025fa3a (Silence 'make checkbashisms', 2020-08-20), we also
allows our users to have that right, too.

Let's fix the problem 'make checkbashisms' reported and allows our users
to have that right, again.

For 'plymouth' case, let's simply run the command inside the if instead
of checking for the existence of command before running it, because the
status is also failture if plymouth is unavailable.

While we're at it, let's remove an unnecessary fork for grep in
zfs-generator.sh.in and its following complicated 'if elif fi' with
a simple 'case ... esac'.

To support this change, also exclude 90zfs from "make checkbashisms"
because the current CI infrastructure ships an old version of
"checkbashisms", which complains about "command -v", while the current
latest "checkbashisms" thinks it's fine. In the near future, we can
revert that change to "Makefile.am" when CI infrastructure is updated.

Érico Rolim 24c12b48a1 config/dracut/90zfs: handle cases where hostid(1) returns all zeros
On systems with musl libc, hostid(1) always prints "00000000", which
will cause improper behavior when the 90zfs module is configured in a
dracut initramfs. Work around this by copying the host /etc/hostid if
the file exists, and otherwise only write /etc/hostid if hostid(1)
returns something meaningful. This avoids zgenhostid creating a random
/etc/hostid for the initramfs, which could lead to errors when trying to
import the pool if spl_hostid isn't defined in the kernel command line.

Furthermore, tag the /etc/hostid file as hostonly, since it is system
specific and shouldn't be taken into account when trying to use an
initramfs generated in one system to boot into a different system.

Replace ZFS on Linux references with OpenZFS
This change updates the documentation to refer to the project
as OpenZFS instead ZFS on Linux.  Web links have been updated
to refer to https://github.com/openzfs/zfs.  The extraneous
zfsonlinux.org web links in the ZED and SPL sources have been
dropped.

cmd/zgenhostid: replace with simple c implementation
It was discovered that dracut scripts and zgenhostid
always generate little-endian /etc/hostid.

This commit provides simple endianess-aware binary
and updates the scripts to use it.

New features include:
 -f flag to force overwrite.
 -o flag to write to different file (for dracut)
 accepting both 0x01234567 and 01234567 values as input

Silence 'make checkbashisms'
Commit d2bce6d03 added the 'make checkbashisms' target but did not
resolve all of the bashisms in the scripts.  This commit doesn't
resolve them all either but it does fix up a few, and it excludes
the others so 'make checkstyle' no longer prints warnings.  It's
a small step in the right direction.

* Dracut is Linux specific and itself depends on bash.  Therefore
  all dracut support scripts can be bash specific, update their
  shebang accordingly.

* zed-functions.sh, zfs-import, zfs-mount, zfs-zed, smart
  paxcheck.sh, make_gitrev.sh - these scripts were excuded from
  the check until they can be updated and properly tested.

* zfsunlock - only whole values for sleep are allowed.

* vdev_id - removed unneeded locals; use && instead of -a.

* dkms.mkconf, dkms.postbuil - use || instead of -o.

Reduce the usage of EXTRA_DIST. If files are conditionally included in

could possibly be included, but this does not apply to EXTRA_DIST,

Add bootfs.snapshot and bootfs.rollback kernel parameters

done from a rescue environment. This patch makes it possible to snap-
shot or rollback the bootfs simply by specifying bootfs.snapshot or
bootfs.rollback on the kernel command line. The operation will be
performed by dracut just before bootfs is mounted.

bash scripts: use /usr/bin/env for bash shebangs
Not all systems / distros have a `/bin/bash`, and these scripts are
more difficult to run at development time.

For example, my system is NixOS which doesn't have a /bin/bash. This
is not a problem for NixOS building ZFS as a package: the build
environment automatically replaces these shebangs with corrected
paths.

The problem is much more annoying at development time: either the
scripts don't run, or I correct them for my local machine and deal with
a perpetually dirty work tree.

Before committing this patch I confirmed there are existing scripts
which use `/usr/bin/env` to locate bash, so I am thinking this is a
safe transformation.

There are a handful of other shebangs in this repository which don't
work on my system. This patch is useful on its own specifically for
`commitcheck.sh`, otherwise I can't validate my commits before
submission.

Here are the remaining shebangs which NixOS systems won't have:

       1274 #!/bin/ksh -p
         91 #!/bin/ksh
         89 #! /bin/ksh -p
          2 #!/bin/sed -f
          1 #!/usr/bin/perl -w
          1 #!/usr/bin/ksh
          1 #!/bin/nawk -f

plus this which will create an invalid shebang in
`tests/zfs-tests/tests/functional/mv_files/mv_files_common.kshlib`:

        echo "#!/bin/ksh" > $TEST_BASE_DIR/exitsZero.ksh

I chose to leave those alone for now, and gauge the interest in this
much smaller patch first.

The fixes for these are easy enough by simply using `/usr/bin/env ksh`:

         91 #!/bin/ksh
          1 #!/usr/bin/ksh

The fix for the other set is much trickier. Quoting the GNU coreutils
manual:

    Most operating systems (e.g. GNU/Linux, BSDs) treat all text after
    the first space as a single argument. When using env in a script it
    is thus not possible to specify multiple arguments.

and not all `env`'s support arguments.

Mine (GNU Coreutils 8.31) does, though this feature is new since
April 2018, GNU Coreutils 8.30:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=668306ed86c8c79b0af0db8b9c882654ebb66db2

and worse, requires the -S argument:

    -S, --split-string=S  process and split S into separate arguments;
                          used to pass multiple arguments on shebang
                          lines

Example:

    $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "sort -nr"
    /nix/[...]-coreutils-8.31/bin/env: ‘sort -nr’: No such file or directory
    /nix/[...]-coreutils-8.31/bin/env: use -[v]S to pass options in shebang lines

    $ seq 1 2 | $(nix-build '<nixpkgs>' -A coreutils)/bin/env "-S sort -nr"
    2
    1

GNU Coreutils says FreeBSD's `env` does, though I wonder if FreeBSD's
would be unhappy with the `-S`:
https://www.gnu.org/software/coreutils/manual/html_node/env-invocation.html#env-invocation

BusyBox v1.30.1 does not, and does not have a `-S`-like option:

    $ seq 1 2 | $(nix-build '<nixpkgs>' -A busybox)/bin/env "sort -nr"
    env: can't execute 'sort -nr': No such file or directory

Toybox 0.8.1 also does not, and also does not have a `-S` option:

    $ seq 1 2 | $(nix-build '<nixpkgs>' -A toybox)/bin/env "sort -nr"
    env: exec sort -nr: No such file or directory

---

At any rate, if this patch merges and the remaining ~1,500 are updated,
the much larger patch should probably include a checkstyle-like test
asserting all new shebangs use `/usr/bin/env`. I also don't mind
dealing with NixOS weirdness if the project would prefer that.
