glabel looks to place a label on the whole disk, but the manpage is
unclear (to me) how the partitions are handled. If I use glabel to
label a disk "test" and this disk has 4 partitions on it, then how is
each partition accessed? testp1...testp4 for gpt?
The other option seems to be to use tunefs or a partitioning tool to
label each partition, which is even more ugly imo.

Look for disk labels, I think glabel is the command. Then you use
/dev/label/mylabel etc for the disks.
Let me know if this isn't enough to find the right man page or spot in
the handbook. I use it in my raid array but am running short on time
right now.

I was getting ready to install the latest FreeBSD 9-RCs image, and I
found that 9 now defaults to using the ahci driver for sata disks.
This would be great if it weren't for the fact that the ahci
driver seems to do dynamic device name assignment as opposed to the
static ones used with the older drivers.
I've looked around on google and while this is mentioned (in old
threads), the "solution" is to use labels or elaborate mapping via
hints which really aren't solutions imo. If I have 15 disks in an
array, I want to be able to label them and know which bay is which
device name. If I have to replace a drive, I have no idea what
dynamic device name it will have when it comes time to partition
(and label, if I were using that). I could probably figure it out
by looking at what disks are used on the system, but that's more
work that it really should be.
Is there a way to use the ahci driver and get static device names?
