Hi Dave, Found that the "sometimes doesn't boot" was caused by my ntfs partition.
Got only two lines in mdadm.conf, one DEVICE and one ARRAY with auto=md at the end. <---- 1st line ----> DEVICE /dev/hd[eg]1 /dev/md0 <---- 2nd line ----> ARRAY /dev/md0 level=raid0 num-devices=2 UUID=de8de1a1:92bd24ff:71f87519:4adf71fd auto=md <---- end ----> => So your sed line gives "md" On dapper it ran without the "auto" part nicely and I just added it after the edgy init script couldn't start the raid. Switched auto= with UUID= but this didn't help.
