Is there a loader.conf entry to enable the static ids, or will the ahci
driver always use static ids if "options ATA_STATIC_ID" is in the kernel
config? I desire to use stock kernels and the 9-rc2 boot iso seems to
not have ATA_STATID_ID set (unless there's a loader.conf value to enable
the functionality)

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.
It seems AHCI driver uses static naming policies if you have 'options
ATA_STATIC_ID' in your kernel configuration. Anyway, I just have one
SATA disk, which the system recognizes as 'ada4'.
I don't know whether this will apply in your case.
Is there a way to use the ahci driver and get static device names?
