"Dangerously" dedicated partitioning omits the slicing part, so if you had mfid0s1[a-g] in 6 and 7, there was a slice. Maybe the mfi driver is different in 8 in terms of representing the disks? > Two issues here why did the naming scheme seem to indicate a more > normal MBR disk layout in bsd 6 and 7. Very strange - if you can check booting from a live system CD or DVD with FreeBSD 6 and 7, and the disks are mfid0s1[a-g], and if you boot into FreeBSD 8, the disks are mfid0[a-g], that's really strange... > Second what is the current status of > dangerously dedicated in 8-stable as i thought support was being dropped. The support has been removed from sysinstall. You can't create dedicated partitions (without slice) with sysinstall, but you can create them manually (e. g. using bsdlabel and newfs). So support isn't dropped at all - dedicated disks just is a new special secret feature. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
