This is correct. > How does one get gpart labels to show up in /dev? They should show up automatically as soon as a drive's partitions have been labeled. When such a partition gets mounted, the label file in /dev will disappear, this is completely normal. I'm not sure, but maybe even if you use the device name for mounting, the label could disappear as the corresponding provider is no longer available for mounting. > Can I simply list the label as /dev/hdd-1TB-root (in the above example) > in fstab and it will happen automagically? Note that depending on the _kind_ of labels, the entry in /etc/fstab has to be in a specific format. Example: /dev/ada1p2 <- device name /dev/gpt/hdd-1TB-root <- label from gpart /dev/label/hdd-1TB-root <- label from glabel /dev/ufsid/1234567890abcdef <- UFS ID You can find more information here: http://www.wonkity.com/~wblock/docs/html/disksetup.html#_the_new_standard_gpt https://www.freebsd.org/doc/handbook/geom-glabel.html -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
