In order to create my own custom Linux ISO (Ubuntu), I have decompressed the Squash file system and would like to make the changes to leave it with a installed and working OpenSSH-Server before re-squashing it again to ISO.  I suppose these changes are:Some binary files in some specific directories.Some config files for the SSH Daemon.Some files corresponding to the keyfiles that are supposed to be generated.Some changes to the system files in order to make the SSH Daemon start on boot.Sumarizing, I would like to change just the same that the classical apt-get installer would change.  If this is possible, how could it be done?
