Subject: re: changing root passwd
We run ATT System 5 R 3.2 and have had the same problem - the `official'
procedure is:
1) Boot the system using the (first) distribution floppy disk.
2) When it asks if you are ready to install Unix, break out by
typing Ctrl-\ (The ATT manual says Ctrl-Break but its wrong!).
3) Run fsck:
# /tec/fsck /dev/dsk/0s1
4) Mount 0s1 (hard disk root partition)
# /etc/mount /dev/dsk/0s1 /mnt
5) You can then edit the passwd file using `ed'
# ed /mnt/etc/passwd
Don't try anything subtle here, all you need is to delete
the `x' on the first line.
6) Unmount the hard disk
/etc/umount /dev/dsk/0s1
7) Remove floppy disk and reboot.
Its a bit fidddly to do, especially when the distribution floppy has
so little of unix on it. It doesn't have `ls' even !. It can be done if
you're reasonably careful.
Have fun!!
