#  @(#)buildroot	1.1 (ULTRIX) 3/2/89
#  Usage: example: sh buildroot ra0 /library/Ultrix
#
#  Description: build the Generic ROOT file system in a dumpimage
#------------------------------------------------------------------
#
#  002 - Nov, 1987 - Tom Tresvik.  
#	Change the interface so that it can be called by the build 
#	script 'buildultrix'.  The ROOT image is produced on the 
#	output pack in .../usr/sys/dist/kitimages/ROOT
#
#  001 - June, 1986 - Lea Fottfredsen & Tung-Ning Cherng
#	   Added in the network remote support.
#
#  000 - March, 31, 1986 - Tung-Ning Cherng
#	   Revised for V2.0.
#
#   	Based on V1.2 'buildroot' - by Greg Tarsa and Bob Fontaine
