So, I easily edited the text in /etc/issue to something more to my liking. This is just text, no meaning.
Watching a cmake session, I noticed the distribution being called, you guessed it: Kali ... Found another file: ~$ cat /etc/os-release PRETTY_NAME="Kali GNU/Linux 2.0 (sana)" NAME="Kali GNU/Linux" ID=kali VERSION="2.0 (sana)" VERSION_ID="2.0" ID_LIKE=debian ANSI_COLOR="1;31" HOME_URL="http://www.kali.org/" SUPPORT_URL="http://forums.kali.org/" BUG_REPORT_URL="http://bugs.kali.org/" Actually a symlink to /usr/lib/os-release So where did I get this? Do I need it? If I do, what should it be for Debian Sid? I had Kali's repos but installed none of their packages. I recall some script with a text-mode menu for treating some of their security packages but I never installed any of them. Script might have touched to two files (be there any others??)
