Can raidtools 0.90 (etc) do recursive RAID AUTODETECT ?

[Piete Brooks]

I've asked before that the AUTODETECT code always look for PSBs in generated
RAID partitions, so that recursive RAID partitions work (e.g. RAID1 10/0+1/1+0)
Does anyone know if this has been done ?
I have started them manually and it seems to work.
Do I just have to HACK it by calling "raidstart -a" before fsck runs ?
