With help from Chris & Ashley I just figured this out-- thanks to both of you. The man page for devfs definitely does not make this clear, BTW: 'Primary' DOS partitons (aka slices) are numbered 1 thru 4, even if you don't actually use them all. 'Extended' DOS partitions can be accessed in FBSD (as in Linux) starting with numbers 5 and above, e.g. /dev/ad0s5, ad0s6... depending on the number of extended partitions you create on your hard disk. With the new devfs kernel these partitions are not visible in /dev *until* you mount them with, e.g., mount_msdos /dev/ad0s6 /mnt or mount_ext2fs /dev/ad0s5 /mnt But there is no clue that these 'devices' exist until you actually mount them. I hope this may save some time for other newbies migrating from the Linux world. Next question: is it possible to create 4.2BSD filesystems on these 'extended' partitions?
