So.... You boot from /dev/da0 and also have a USB stick on /dev/da0?
That's.....  Odd...

If you're using GPT on the drive, you can use `gpart (8)` to set a
label that will appear under `/dev/gpt/`.

As /u/dddddavidddd said, use GPT partition labels and then you just
use the label in your fstab and it won't matter which device it is.

`gpart show`   will show you all your devices and their partitions.

`gpart modify -l LABELNAME -i PARTITIONNUM GEOM`  will set the label
for the GEOM (the disk) and the index or partition number.

Then in fstab you can mount with: /`dev/gpt/LABELNAME`  as the device.

note: FreeBSD does it weird. GPT labels won't show up until a system
uses them, so you have to take a leap of faith they're there.

note 2: you'll find a lot of references to glabel for labeling disks
or partitions. This is a FreeBSD specific way of doing things and
isn't recognizable by Linux or Windows. GPT partition labels will be
visible to Linux.

note 3: this is going under the assumption you're using GPT partitions
on a disk. There is very little reason why you shouldn't be, but not
everyone uses them.
