Incremental: add --export handling.
If --export is given with --incremental, then
MD_DEVNAME
is output which gives the name of the device (in /dev/md) that
is the array (or container) that the device would be added to.
Also
MD_STARTED
is set to one of
no
unsafe
yes
nothing
to indicate if the array was started. IF MD_STARTED=unsafe
then it may be appropriate to run
mdadm -R /dev/md/$MD_DEVNAME
after a timeout to ensure newly degraded array are started.
If
MD_FOREIGN=yes
it might be appropriate to suppress this as the array is
probably not critical.
