i cannot restore the system back up 1

[demetrio]

i am running a sco unix v3.2 4.2. someone programmer
delete from the root disk some files and the system cannot boot not even the single user. i boot from floppy using
the root and boot diskette.
i can see all the file systems included the root file system
i mounted the root file system to the /mnt directory of the diskete using mount /dev/hd0root /mnt
i go to the mounted directory

cd /mnt to my root disk.
the problem begins now. i try to restore the system back up
but the files don't go to the /mnt directory (the mounted directory of my root disk) but to the / directory which is the floppy.
i backup my system using the command

find / -depth -print |cpio -ovcB - O /dev/rct0

and i try to restore them using the command

cpio -iBudvcm -I/dev/rct0
or
cpio -icvdum -I/dev/rct0

any ideas who i can restore to the original location?
to the /mnt directory which is my root disk?

moreover i try (i am not sure if that can works)
to copy from the boot and the root disketes files to root directory of my disk. do you know , if it is possible of cource, which files shall i copy in order to boot not from the floppy but from the hard disk ?
i managed to copy all the files (boot , unix /etc) from boot diskette but i i dont now which files
shall i copy from the root diskete. some files cannot be copied from the root diskette
if i can boot from my hard disk to single user its easy from me then

thank you and i hope that you will understand what iam asking. (my english are very bad)

I don't remember if the 4.2 cpio admits the -A option (removing of leading / in pathnames).
If yes, then make /mnt your current directory (cd /mnt), make sure that all the backuped filesystem are mounted and go for the restore.
To know how the diskette's kernel see the disk's filesystem you may take a look at divvy.
I guess something like:
mount /dev/hd0u /mnt/u

Hope This Helps, PH.

You can copy the boot and unix files to /mnt and they will be used on the next hard drive boot.
Unmount the hard drive before you quit out of the floppy system so everything will be clean.

i copied the boot the unix files from the boot diskette
to the hd0root disk (the mounted dierctory of the diskette}
i tried to copy the the directories and the files from the root diskette but some of them cannot be copy
most of the files of the /dev, /bin directories.
files such us -sh, hd01....etc
i umount the file system and i shutdown the system using haltsys
with the files i had copy i try to boot from the hd
the sytem goes to boot
i press to {enter} to boot but nothing goes on.
with the dir command i can see the files that i have copied
i press ./unix
it writes that it boots not from the hard disk hd(40)
but from the floppy fd(60)but it seems to try to boot from the hd because i dont have the boot diskette to floppy.
as soon as the system by pass the kernrel it stucks
just a little before it enters the single user.
do you know which files shall i copy from the boot and root diskette in order to enter the single user from my hard disk?

per the manual the required files are /boot , /unix , and /etc/default/boot.

Strongly suggest that you refer to section 22, solving boot problems as it has specific instructions for the recovery.
