Can glabels, gpt, and zfs all work together? I have a system where I have disks with 4 gpt partitions. Partitions 2 and 3 are part of gmirror arrays, and partition 4 is part of a zfs pool. glabel says it writes to the end of the partition, which I believe zfs also writes to doesn't it? Rob

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 fu

AHCI driver and static device names

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 old
