# These are examples of how to configure devices using /etc/rc.d/devfs.
# The first parameter is always the action to take, the second is always the
# existing device created by devfs, and the last is what you want to change.
# The name of the action is only significant to the first unique character.
#
# Examples:

# Historically X depended on this, but version 4.3.0 doesn't seem to anymore
#link ttyv0 vga

# Commonly used by many ports
#link cd0 cdrom
#link cd0 dvd

# Allow a user in the wheel group to query the smb0 device
#perm smb0 0660

# Allow members of group operator to cat things to the speaker
#own speaker root:operator
#perm speaker 0660
perm cd0 0660
perm xpt0 0660
perm pass0 0660
own vboxnetctl root:vboxusers
perm vboxnetctl 0660
