This is a hack, something that you would commonly find in Linux code and
is neither a proper or viable workaround for the naming of labels.
Instead, using glabel(8) the admin/user can create a local label to
FreeBSD that does not change the original nor does it carry over to any
other OS that does not understand geom_label's.
From the manual page:
label Set up a label name for the given provider. This is the
``automatic'' method, where metadata is stored in a provider's
last sector. The kernel module geom_label.ko will be loaded if
it is not loaded already.
Stripping characters no matter what they are with a sysctl is overkill
and does not scale well, all the while - presenting false information to
the user. I would highly advise against this. If the user does not like
the label that appears in msdosfs/{LABEL} then they are free to change
that at their own will. I see presenting the label as it is to the user
``important''. Lets not try to prevent a foot shooting but instead
document the case in the manual. Also if they are using FreeBSD and they
are also adding a mount-point to fstab(5) for a geom_label then
intelligence lurks within.
