I haven't tried with just /boot, but I have a machine with a 1.5GB mirror across four disks for the root filesystem, with a graid5 across the remaining space for the other filesystems. That works just fine. As far as I know, however, no boot loader can understand software-striped or software-raid5ed filesystems, given that it would essentially need to implement the relevant geom providers itself. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net Furry Peace! - http://wwww.fur.com/peace/
