How to edit /etc/inittab?
Clash Royale CLAN TAG#URR8PPP
I want to edit /etc/inittab in order to get a login prompt on the serial console once the system boots. By default, inittab file complains to be ro.
I tried both gksudo gedit /etc/inittab and sudo vi /etc/inittab and seemed to be properly configured. However, when I opened file after that with gedit, I saw no difference.
Any ideas?

Try this: Open terminal, then type su and type your root user password. After this:
vi /etc/inittab
In my case this works but I'm using CentOS.

From your question it sounds like you weren't saving before exiting Vi. After you are done editing inviyou need to save changes, typically with an [Esc] thenw(to write changes), you can combine withqas follows:wq!(write, quit, and ! means don't confirm).

You must also do # update-initramfs -u, to my understanding, to have the changes take effect (on Debian Linux, anyway).

vi you need to save changes, typically with an [Esc] then w (to write changes), you can combine with q as follows: wq! (write, quit, and ! means don't confirm).– LawrenceC
