Below you refer to the old-style RAID in the stock kernels which is considered
unstable or at least out-dated by many. Quite a few (most ?) people on this
list use the new-style RAID, referred to as 0.90 RAID, and that's where the
``really force'' stuff comes into the picture.
See http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/ for an explanation.

Yep

No why ? They're about to be combined into a new block device, they're
not in their final form yet.

Nope. mdadd is old-style RAID.

Yes ! With 0.90 RAID there is one configuration file, /etc/raidtab, and even
this will be unneeded once the array is up running, because the new-style RAID
keeps the configuration in superblocks on the devices participating in the
array. (But you might want to keep the config file anyway - just in case :)

The option will be printed for you once you install both a kernel with new-style
RAID, and the proper raidtools for that kernel. Again, see the HOWTO.

Hope this helps you more than it confuses you.
