If mdadm.conf contains
HOMEHOST <ignore>
or commandline contains
--homehost=<ignore>
then the check that array metadata mentions the given homehost is
replace by a check that the name recorded in the metadata is not
already used by some other array mentioned in mdadm.conf.
This allows more arrays to use their native name rather than having
an _NN suffix added.
This should only be used during boot time if all arrays required for
normal boot are listed in mdadm.conf.
If auto-assembly is used to find all array during boot, then the
HOMEHOST feature should be used to ensure there is no room for
confusion in choosing array names, and so it should not be set
to <ignore>.

Currently Incremental_container is being called after adding each disk.
In the imsm case where spares are not tracked in the raid_disks field we
can use --no-degraded to block premature assembly.

Metadata formats like imsm work in concert with platform firmware and
hardware, so provide a way for mdadm to display this info to the user.

Its cumbersome to determine which devices to wait for in a system shutdown
script, so hook up --scan.

Previously it was possible to set the WRITEMOSTLY flag when
adding a device to an array, but not to clear the flag when re-adding.
This is now possible with --readwrite.

.UR URL
text
.UE
is meant to create a hyperlink from the 'text' to the 'URL'.
But I wanted just to have the URL, so UR isn't really the right
tool - the URL gets displayed twice.
So just display the URL in bold and assume man2html etc can recognise
it and do the right thing.

Root file systems backed by external metadata arrays need to be
explicitly checkpointed near the time the rootfs is marked readonly as
userspace will not have an opportunity to react to the final shutdown of
the array.

For use in distro shutdown scripts with a RAID root file system.
Returns immediately if the array is 'readonly', or not an externally
managed array. It is up to the distro's scripts to make sure no new
writes hit the device after this returns 'true'.

Two places that should have been .B or .I were .M, which of
course is an error.
So fix these and that the opportunity to be more consistent
with highlighting of "mdadm". Make it always italic except when
used as a literal example, then bold.
udev likes to get information about a device as key=value pairs so it
can create disk/by-id links etc. So add --export flag which causes
the output of --detail to easily parsable.

nroff formats "-" as the very short hyphen used for hyphenated terms
and for splitting a word across two lines. When you want a literal
ASCII "-", like for typing on a command line, you're supposed to use
"\-" instead.
Yeah, it sounds pedantic, but it actually makes a difference. With
modern Unicode-capable terminals, "man" actually renders these with
different characters, so if you try to search for "--create" in your
favorite pager, you won't find it unless the nroff source says
"\-\-create". This discrepancy doesn't generally show up with
non-Unicode terminals.

Option names and example command lines seem to be boldface most of the
time, fix up the few that weren't.

\(em renders as "--" in ASCII, and a nice em dash (i.e., a dash the
width of the letter "m") in more capable formats like PostScript.
