From: hlu@eecs.wsu.edu (H.J. Lu) Subject: new README for HLU bootable root disk. Date: 29 Sep 1992 22:53:32 GMT
The main change is
(cd /; /mnt/bin/tar cf - ./bin ./dev ./etc ./lib ./usr ./tmp ./vmlinux) | (cd /mnt; /mnt/bin/tar xvvf -)
That is in one line.
BTW, I will update the kernel to 0.98 once I get it compiled.

===============
These are bootable root disks for Linux. Kernel is 0.97 patch level 6
with Ted's one line fix for serial.c. There are some basic binaries on
root disks, all of which are linked with jump table 4.1. They are on
tsx-11.mit.edu under pub/linux/GCC/rootdisk.
This is a partial list of what are on root disks.
1. bash 1.12
2. gnu tar 1.10 (tar.Z)
3. compress 4.2.3
4. elvis 1.6
5. doshell, chmod, chown, cp, ls, mv, rm, and ln.
6. mount, umount, swapon
7. more
8. ps and free
9. mkfs, mkswap, fsck and fdisk
There are two versions of root disks, one, 3rootdisk.Z, for 1.44MB drive,
the other, 5rootdisk.Z, for 1.2MB drive. Please do
1. uncompress [3|5]rootdisk.Z.
2. rawrite or dd it to a floppy disk.
3. boot that floppy disk.
If you want to use it to install Linux on your HD, you are on your own.
Everything is there. But you have to know how to use them.
Since there is no enough room on a 5.25" floppy, I left out init, getty
and login stuffs. After booting Linux off a 5.25" floppy, do
su
doshell /dev/tty2 bash&
You will get another virtual console on /dev/tty2.
Suppose you want to install Linux on partition, /dev/hdxx, whose size
is yyyy K bytes, you can use fdisk to find it out, you do
mkfs /dev/hdxx yyyyy
mount /dev/hdxx /mnt
cd /mnt
mkdir bin
cp /bin/tar.Z /mnt/bin
chmod 755 /mnt/bin
uncompress /mnt/bin/tar
(cd /; /mnt/bin/tar cf - ./bin ./dev ./etc ./lib ./usr ./tmp ./vmlinux) | (cd /mnt; /mnt/bin/tar xvvf -)
You have to do these:
cd /lib
cp libc.so.4.1 /mnt/lib
cp libm.so.4.0 /mnt/lib
This will save some disk spaces since cp can make holes and tar can't.
You now should edit /mnt/etc/fstab to make sure /dev/hdxx will be
mounted as root. There are some examples in /mnt/etc/fstab. After that,
do
cd /mnt/etc/lilo
rm map boot.????
./lilo -r /mnt -b /dev/hdxx -i boot.b -v -v -v /vmlinux
Now, you can boot Linux from your HD. To install the other stuffs
should be very trivial now since you have tar and compress on your HD,
and you can boot Linux off your HD. I suggest you get my bonuses come
with jump table 4.1.
I will try to update my root disk regularly with Linus' new kernel.
This root disk works on my machine with 100MB IDE drive. I don't know
anything about your machine or SCSI. Wish you good luck.
Correct me if I am wrong. Tell me about your story.
Thanks.
