# This executable automount map handles removable devices. 
# 
# It reads a configuration file which maps symbolic names to device identifiers.
# Removable devices are identified by their serial number, while "static"
# devices (such as DVD drives) are identified by their device path.
#
# The first example creates a "stick" entry for partition 1 of USB mass storage
# device DEF107679C83. The second mounts each partition under a directory
# named after its partition number.
#
#    stick  scsi-usb  DEF107679C83:1  -fstype=auto,sync
#    rstick  scsi-usb  DEF107679C83  -fstype=auto,sync
#
# This example creates a "dvd" entry for a SCSI DVD drive:
#
#    dvd  dev  /dev/scd0  -fstype=iso9660,ro
