# To make this event script work add the apache2_dav.conf file
# from /usr/share/doc/cryptobox/conf-examples/ to your apache
# configuration directory (e.g. /etc/apache2/conf.d)
#
# This event script manages apache webdav
# - after mounting: add the new webdav share
# - before umounting: disable and remove the webdav share
#

#
# Params: $event $device $volume_name $volume_type $mount_dir
#
# event: premount | postmount | preumount | postumount
# device: name of the device
# volume_name: name of the volume
# volume_type: plain | luks
# mount_dir: mount directory
