I am using FreeBSD 2.1 on a machine and was relabelling the disk to 
modify the boot blocks, it seems that the disk drive name was also
inadvertantly changed.

Could anyone enlighten me as to the difference between for example
wd0e and wd0s1e?  They have different device numbers but after my
screw-up with the disklabel and I got wd0s1e changed to wd0e (and all
the other partitions too) and modified fstab to the wd0xx names from
wd0sxx name everything still seems to work.

I looked at the handbook, the FAQ, the man pages, and the kernel
sources but I didn't seem to find an explaination for the difference
between the wd0xx and wd0s1xx partitions names.  I suspect that
it may be related to some extra filesystem property that is new
in the 2.1 or newer release.

Anyone care to shed som light on this?

Dennis.
