Why do modules get loaded when I log in?

[nephros]

Hi.

This puzzles me:

On a freshly booted system, whenever I log in as root and do a lsmod, I see four modules loaded: usbcore and three sound modules. This is OK as I specify those in modules.autoload.

But when I log in as regular user for the first time, a lot of device driver modules get loaded:
floppy, ide-cd, ide-scsi, scsi_mod, sg, sr_mod, sd_mod, cdrom.

These are the modules corresponding to my three drives: the floppy, an IDE cdrom and an USB CD-burner, using SCSI-emulation.

My regular user is member of the groups corresponding to those devices: floppy, cdrom and various cd burner groups.

Still, I would very much like those modules NOT be loaded at login time, but I have not been able to firgure out what triggers their loading. I am suspecting PAM, but cannot be sure.

Please help?

I have this "problem" too on my laptop. I suspect that it is caused by /etc/devfsd.conf for the permission checks. Try adding a user and do not add it to any group, if the modules don't get loaded when this new user log in it is caused by devfsd. It's not a solution but you would be closer to the troublemaker.
