>Description:
Applying a glabel to a disc, partitioning with gpart and setting up a journal onto a partition ends up with the label for the disc to disappear after reboot.

GEOM label and journal are loaded via loader.conf:

geom_journal_load="YES"
geom_label_load="YES"

>How-To-Repeat:
# glabel label -v array0 /dev/da0
Metadata value stored on /dev/da0.
Done.

# gpart create -s gpt label/array0
label/array0 created

# gpart add -t freebsd-ufs label/array0
label/array0p1 added

# gjournal label /dev/label/array0p1

# newfs -O 2 -J /dev/label/array0p1.journal

# ls /dev/label
array0			array0p1		array0p1.journal

# glabel list
