* Debian Preseed Configuration
|
||
|
|
|
||
|
|
This Git repository contains a preseed configuration file (preseed.txt) that can be used to automate the installation of Debian on default machines. The preseed file is based on the official DebianInstaller/Preseed documentation, which can be found [[https://wiki.debian.org/DebianInstaller/Preseed][here]].
|
||
|
|
|
||
|
|

|
|
|

1. When the graphical installer boot menu appears, select the "Help" entry.
|
||
|
|
2. You will get a generic help screen with a boot: prompt at the bottom.
|
||
|
|
3. Type the following command, replacing the URL with the address to your preseed configuration file:
|

#+begin_src shell

auto url=http://webserver/path/preseed.cfg
|

|
|
echo "sh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKqc9fnzfCz8fQDFzla+D8PBhvaMmFu2aF+TYkkZRxl9 tuan@genesis-2022-01-20" > /target/home/user/.ssh/authorized_keys
|
||
|
|
chown -R user:user /target/home/user/.ssh/
|
||
|
|
chmod 700 /target/home/user/.ssh/
|
||
|
|
chmod 600 /target/home/user/.ssh/authorized_keys
|
||
|
|
#+end_src
|
||
|
|
|
||
|
|
These commands will create an .ssh directory in the user's home directory, add an authorized SSH key, and set the appropriate permissions.
