Login


Hi!

the init procedure of common distribution (MDK 8.2 in my case) is complex enough for one that it only wants to learn linux through "the construction" of a mini system floppy based.
I have been copied directly my init, login, mingetty, ecc... from my mdk 8.2 distribution and obviously (this is my problem when i get my login prompt and try to login as root, my screen clean up and i'am prompted again!!! hostname login:

My system (mdk 8.2) use pam, and (i think) i've been copied everything is needed for that!

Well for one I'd start by stopping it from clearing the screen, so you can see any error messages the login program might print before it closes. This is usually done by a line of escape codes in the /etc/issue file.
login does need the following files to work properly:
/var/run/utmp
/var/log/wtmp
/var/log/lastlog

So you might want to do a touch on those files and then chmod them to 644. I don't know what pam all needs but it shouldn't be too hard to get it running without pam.
Although it's very possible to do I really wouldn't base a floppy distribution off something like mandrake. I'd probably go for building an lfs system and then basing off of that. It allows you to start with a very minimal system which you have build yourself so you know where all the pieces and bits are.

Well if you aren't using a bootloader and can't set the init parameter then the default action in the kernel is to start one of these in the following order:
/sbin/init, /etc/init, /bin/init, /bin/sh

So if you don't have a init script anywhere then it will end up starting a normal sh. On most linux systems /bin/sh is just a link to bash.
But it depends on what you want to do with the floppy distribution you are creating, whether you want to add the whole login thing through the init script. You could also just modify the /etc/inittab file to start up different processes on each terminal instead of having it spawn a tty process which waits for a login.
