So here you go: You will require One (1) Linux machine and the root password for it. --- begin --- #!/bin/sh FILE=/tmp/ramdisk.bin MOUNT=/mnt/ramdisk # (0) Ensure the mount point exists. if [ ! -d $MOUNT ]; then mkdir $MOUNT; fi # (1) Create a ramdisk of appropriate size. dd if=/dev/zero of=$FILE bs=1024 count=400 # (2) Create a filesystem in it. mke2fs $FILE # (3) Mount it mount -o loop $FILE $MOUNT # (4) copy files into it. echo Now copy your files into $MOUNT bash # (5) unmount unmount $FILE --- end --- Ensure that you have /dev/console, /sbin/init, /dev/tty0 and a /proc directory is probably also wise. It's probably easiest to copy them from a ramdisk already available, but here's an ls -lR of one: # ls -lR /mnt/cdrom2 /mnt/cdrom2: total 15 drwxrwxrwx 2 root root 1024 Oct 18 13:23 dev drwxrwxrwx 2 root root 12288 Aug 22 15:12 lost+found drwxrwxr-x 2 root root 1024 Oct 19 12:21 proc drwxrwxrwx 2 root root 1024 Jan 24 17:26 sbin /mnt/cdrom2/dev: total 0 crwxrwxrwx 1 root tty 5, 1 Oct 18 13:23 console crwxrwxrwx 1 root tty 4, 0 Oct 18 13:23 tty0 crwxrwxrwx 1 root tty 4, 1 Oct 18 13:23 tty1 crwxrwxrwx 1 root tty 4, 2 Oct 18 13:23 tty2 crwxrwxrwx 1 root tty 4, 3 Oct 18 13:23 tty3 crwxrwxrwx 1 root tty 4, 4 Oct 18 13:23 tty4 crwxrwxrwx 1 root tty 4, 5 Oct 18 13:23 tty5 crwxrwxrwx 1 root tty 4, 6 Oct 18 13:23 tty6 crwxrwxrwx 1 root tty 4, 7 Oct 18 13:23 tty7 crwxrwxrwx 1 root tty 4, 8 Oct 18 13:23 tty8 crwxrwxrwx 1 root sys 7, 0 Oct 18 13:23 vcs0 crwxrwxrwx 1 root sys 7, 1 Oct 18 13:23 vcs1 crwxrwxrwx 1 root sys 7, 2 Oct 18 13:23 vcs2 crwxrwxrwx 1 root sys 7, 3 Oct 18 13:23 vcs3 crwxrwxrwx 1 root sys 7, 4 Oct 18 13:23 vcs4 crwxrwxrwx 1 root sys 7, 5 Oct 18 13:23 vcs5 crwxrwxrwx 1 root sys 7, 6 Oct 18 13:23 vcs6 crwxrwxrwx 1 root sys 7, 7 Oct 18 13:23 vcs7 crwxrwxrwx 1 root sys 7, 8 Oct 18 13:23 vcs8 crwxrwxrwx 1 root sys 7, 128 Oct 18 13:23 vcsa crwxrwxrwx 1 root sys 7, 129 Oct 18 13:23 vcsa1 crwxrwxrwx 1 root sys 7, 130 Oct 18 13:23 vcsa2 crwxrwxrwx 1 root sys 7, 131 Oct 18 13:23 vcsa3 crwxrwxrwx 1 root sys 7, 132 Oct 18 13:23 vcsa4 crwxrwxrwx 1 root sys 7, 133 Oct 18 13:23 vcsa5 crwxrwxrwx 1 root sys 7, 134 Oct 18 13:23 vcsa6 crwxrwxrwx 1 root sys 7, 135 Oct 18 13:23 vcsa7 crwxrwxrwx 1 root sys 7, 136 Oct 18 13:23 vcsa8 /mnt/cdrom2/lost+found: total 0 /mnt/cdrom2/proc: total 0 /mnt/cdrom2/sbin: total 1036 -rwxr-xr-x 1 willy guests 245760 Jan 18 02:46 ab -rwxr-xr-x 1 willy guests 237568 Jan 18 02:46 hellow -rwxr-xr-x 2 root root 283957 Jan 18 02:31 init -rwxr-xr-x 2 root root 283957 Jan 18 02:31 sash
