PR #8114 quoted the ${ENCRYPTIONROOT} parameter to ensure we don't
lose spaces when unlocking root filesystem in the off chance that
it has a space in its name.
Unfortunately, dracut and initramfs-tools do not actually get the
quotes from the cmdline. If we use root=ZFS="root pool/filesystem
name" the script still only sees root=ZFS=root and no quotation
marks.
Because + is a reserved character in ZFS, it's used as a
placeholder for spaces in the kernel cmdline. In this way,
root=ZFS=root+pool/filesystem+name will properly expand by
replacing the character with sed (POSIX compliant method).

Issue #8114Closes#8117
- 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

Closes#4558Closes#4562
The dracut code is analogous to the initramfs code and as such
it should be located in the contrib with initramfs for consistency.
