No. It means that GEOM_LABEL has created a named device in
/dev/msdosfs/flashdrive. 

This is easier to use then e.g. /dev/da0s1. Consider the case where you
have two USB mass storage devices. One will be da0, the other da1, da0
being the one that was plugged in first. The label 'flashdrive' on the
other hand won't change unless you change it.

If you use 'mount_msdosfs -m 644 -M 755 /dev/msdosfs/flashdrive /mnt'
you can keep using this command (e.g. put it in a script) as long as you
don't change the label.

I don't think so, but you can check it with

% mount -v

if anything has been mounted.

Manual mount seems to have higher priority. Refer to /etc/fstab
to define "standard" mount points if you like, for example:

/dev/fd0/media/floppy   msdosfs rw,noauto   0   0
/dev/acd0   /media/cdromcd9660  ro,noauto   0   0
/dev/acd0   /media/dvd  cd9660  ro,noauto   0   0
/dev/acd1   /media/writer   cd9660  ro,noauto   0   0
/dev/cd0/media/pcd  cd9660  ro,noauto   0   0
/dev/da0/media/pd   ufs rw,noauto,noatime 0 0
/dev/da1/media/jaz  ufs rw,noauto   0   0
/dev/da2s1  /media/stickmsdosfs rw,noauto,noatime 0 0
/dev/da2/media/cam  msdosfs rw,noauto,noatime 0 0
/dev/da3s1  /media/card msdosfs rw,noauto,noatime 0 0

As far as I do understand, GEOM provides these messages to allow
some kind of auto-mounting service (usually coming with KDE or
Gnome) to take some "title" of the media (data carrier identifier)
to create the mount point; I saw something similar with PC-BSD
when CDs, DVDs or USB sticks had been inserted, the mountpoint
was something like /media/The Title of The Disc (including the
ugly whitespaces) or /media/USB0001. Or, as your example seems
to show, the label is a combination of the type of the media and
the filesystem it uses...


If you don't run any of these automounters, the messages don't
seem to hava any effect. But I'm not sure, I've never seen them
on my 7.x system...


Maybe "man geom" will tell you more.
