Make an simple install script for my pc LFS 6.5
 

Since I'm having a lot of hickups installing my pc with LFS and have to begin over and over again I was wondering if it were possible to make a simple bash script that I write. If I have to begin again I can simply start the script, let the computer run until the point where it went wrong.


When I install my pc I copy all the commands to a text file that I make executable.

The only problem I see so far is to make the lfs username and the password because the shell will wait for input (the password).


Is there some way to provide the shell a password or to give a command to create a password file?

Something like:

If you create the account, add the -p switch to useradd. Just get the
encrypted version of your password from /etc/passwd or /etc/shadow.

Otherwise you could use sed to replace your line in /etc/passwd or
/etc/shadow with your version of the encrypted password.
