I've found some rather nifty instructions on setting up softRAID on linux (https://raid.wiki.kernel.org/index.php/RAID_setup
). But I can't discern whether the boot device is/can/or should be part of the raid. I presume I will download, install and configure mdadm while running a normal /dev/sdx device. Should the boot device be a physically separate drive? Can the RAID be set up on top of and incorporate the boot device? Has anyone done this?
