Only generic labels show up in /dev/label.  GPT labels show up in 
/dev/gpt, filesystem labels show up elsewhere depending on type.  See 
glabel(8).  Also, be aware that GEOM will hide some labels when a device 
is mounted.

As for why bsdinstall does not use them, I don't know.  My guess would 
be that it's desired but not yet implemented.  There are several 
complicating factors like the multiple types and locations of labels. 
GPT labels, the least-intrusive kind, are only available on disks 
partitioned with GPT.
