DEVFS and serial numbers
Initial serial number support is now on master. Serial numbers show
up in the /dev/serno directory. All CAM and NATA drives which attach
with serial numbers will show up. Note that many USB drives do not
report serial numbers and may not show up in any meaningful way.
The original drive names, i.e. da/cd/ad* also still show up in /dev,
of course.
Over the course of this week I will be tying the serial number support
into a new /etc/devtab mechanism that will allow physical drives to
be named and mounted by name from the fstab.
Ultimately this will tie into a larger iSCSI mechanic which will
allow drive mobility. We probably won't have iSCSI root-mount support
working for the release, but you never know :-). Antonio's iSCSI work
is slated for integration in the next two weeks.
