/*
 * install.c
 *
 * Last hacked 07/01/93, COH 4.2-Alpha
 *
 * Install COHERENT disks on a system.
 * This is the back end of the initial COHERENT installation procedure;
 * the first part is in build.c.
 * Without the -b option, it installs an update to an existing COH system.
 * If -b or -u selected, suppress copying of files from /compressed directory
 * on floppies and actually uncompress and unarchive them into place.
 * Uses common routines in build0.o: cc install.c build0.c
 * Usage: install [ -bdv ] id device ndisks
 * Options:
 *	-b	Build: special processing for build, part 2.
 *	-d	Debug, echo commands without executing
 *	-u	Update: special processing for build, part 2.
 *	-v	Verbose
