90cf1dddb2 Actually support --syslog 
Fixes-debian-bug: 402457 (part)

All the code is there, and it works for '-y', but for some reason,
"syslog" was missing from the long_options.

b5e3d1901f Remove some unused interfaces to the metadata handlers. 
This stuff has never been used (at least as far as git history can
see).  I wonder why it was there...

67a8c82d60 Make Assemble/Force work on raid6 with 2 missing devices. 
Previously it onl worked when one missing device.
Also split the "force" update_super method into two and it
is really serving two functions.

60e1bc1a33 Fixed problems that could cause infinitel loop with auto assemble. 
If an auto-assembly attempt failes because the array cannot be
opened or because the array has already been created, then we
get into an infinite loop.

2790ffe38a Document that the default metadata version can be overridden in config file. 
From: Goswin Brederlow <brederlo@informatik.uni-tuebingen.de>

This is already mentioned in the config documentation, but not in the
place when the normal default is mentioned.

It can be increased further, but that takes a bit more code
so will wait for 2.6.

1cac4c1b55 Don't trigger and error on -As if all arrays are already started.

Put another way, if we find any active arrays, then assume things are
going as planned.

435d4ebb2e Mdassemble improvements 
From: Luca Berra <bluca@comedia.it>

- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
  stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
  This is useful if they are started read-only as is best at boot-time.

partitions is as given.  This is useful in 'CREATE' in

d2df86e0a7 Improve the message when mdadm detects similar superblocks 
If they are for a partition and a whole device (common case)
they old message doesn't really cover the situation.  So add
the "overlap" option to the text.
Also detect whether the device list was in mdadm.conf and
act accordingly.

c56d3db4d3 Remove indeterminism from names in --examine --brief output. 
It is much better for this sort of thing to be predictable
rather than depending on what devices exist, especially as
these days entries in /dev/ often don't pre-exist.
So make it always
   /dev/mdX

for version0 superblocks.

Version1 are always /dev/md/NAME

 code was ever in there)

7eae7080e2 Work around bug in --add handling for version-1 superblocks 
In 2.6.17 (and prior), the dev_number is ignored when a device
is added to an active array.  Rather the first free number is used.
So we work around this by making sure we use the first free
number for dev_number.
