1#!/bin/sh 2# 3# This script generates a "memstick image" (image that can be copied to a 4# USB memory stick) from a directory tree. Note that the script does not 5# clean up after itself very well for error conditions on purpose so the 6# problem can be diagnosed (full filesystem most likely but ...). 7# 8# Usage: make-memstick.sh <directory tree> <image filename> 9# 10# $FreeBSD: stable/10/release/amd64/make-memstick.sh 293723 2016-01-12 02:12:40Z gjb $ 11# 12 13PATH=/bin:/usr/bin:/sbin:/usr/sbin 14export PATH 15 16if [ $# -ne 2 ]; then 17 echo "make-memstick.sh /path/to/directory /path/to/image/file" 18 exit 1 19fi 20 21if [ ! -d ${1} ]; then 22 echo "${1} must be a directory" 23 exit 1 24fi 25 26if [ -e ${2} ]; then 27 echo "won't overwrite ${2}" 28 exit 1 29fi 30 31echo '/dev/ufs/FreeBSD_Install / ufs ro,noatime 1 1' > ${1}/etc/fstab 32echo 'root_rw_mount="NO"' > ${1}/etc/rc.conf.local 33makefs -B little -o label=FreeBSD_Install ${2} ${1} 34if [ $? -ne 0 ]; then 35 echo "makefs failed" 36 exit 1 37fi 38rm ${1}/etc/fstab 39rm ${1}/etc/rc.conf.local 40 41unit=$(mdconfig -a -t vnode -f ${2}) 42if [ $? -ne 0 ]; then 43 echo "mdconfig failed" 44 exit 1 45fi 46gpart create -s BSD ${unit} 47gpart bootcode -b ${1}/boot/boot ${unit} 48gpart add -t freebsd-ufs ${unit} 49mdconfig -d -u ${unit} 50 51
