- This file tells you how to create an emergency boot disk which will give
- you a root shell if you boot from it, without the need to know the root
- password (but you must have access to the keyfiles while creating this
- disk!). However, this will only work if all keyfiles are still intact!
-
- o Format a floppy and make it bootable using the 'Install' command.
-
- o Copy the necessary files on it so it's directory tree looks like this:
-
- C (dir)
- Assign
- CLI
- Mount
- Devs (dir)
- DOSDrivers (dir)
- MU0
- S (dir)
- Startup-Sequence
- .MultiUser.keyfile
-
- o The files 'MU0' and 'Startup-Sequence' can be found in the
- 'Emergency/Devs/DOSDrivers' and 'Emergency/S/Startup-Sequence'
- directories respectively. The file '.MultiUser.keyfile' can be found
- on any partition you did protect with MultiUser. The other files
- should reside on your Workbench partition.
-
- o Edit the file '.MultiUser.keyfile' and make the second and third line
- empty; do NOT remove these lines, they must exist but be empty! This
- keyfile is the key of your system.
-
- o Edit the file 'S/Startup-Sequence' and apply the changes mentioned in
- the comments.
-
- o Make 'C/CLI' owned by root using the 'SetOwner' command.
-
- o Set the set uid bit ('U') for 'C/CLI' and make it readable for everyone
- using the 'MProtect' command.
-
- o Test your emergency boot disk.
-
- o Keep the disk in a safe place!

- Special thanks to Ingolf Koch for the inspiration.
