# Step 1 - Load the LOMAC LKM.
#

insmod /opt/lomac/bin/lomac_mod.o

#
# Step 2 - Create the /dev/lomac device with the appropriate major/minor
#          device numbers.  The utility programs supplied with LOMAC
#          use /dev/lomac to communicate with the LOMAC LKM.  When it is
#          loaded, the LOMAC LKM registers itself as a character device
#          driver and asks the kernel to assign it a free major device
#          number.  This script can determine which number the LOMAC
#          LKM received by inspecting /proc/devices.  This script must
#          then create the /dev/lomac device with the appropriate
#          major device number.
#


rm -f /dev/lomac
awk '$2 == "lomac" { system( "/bin/mknod /dev/lomac c " $1 " 0" ) }' /proc/devices
