If it has the same meaning, why not leave it called 'DEVICE'???
the idea was to warn people that write
DEVICE /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1
ARRAY /dev/md0 .......
that it might break since disk naming is not guaranteed to be constant.
However, there is at least the beginnings of a good idea here.
If we assume there is a list of devices provided by a (possibly
default) 'DEVICE' line, then
DEVICEFILTER !pattern1 !pattern2 pattern3 pattern4
could mean that any device in that list which matches pattern 1 or 2
is immediately discarded, and remaining device that matches patterns 3
or 4 are included, and the remainder are discard.
The rule could be that the default is to include any devices that
don't match a !pattern, unless there is a pattern without a '!', in
which case the default is to reject non-accepted patterns.
Is that straight forward enough, or do I need an
order allow,deny
like apache has?
I think that documenting the feature would be enough
