This is a default for the initrd's linuxrc. You installed one of our
official 2.4.x kernels.

Sense? This prompt is good for loading some modules when the
autodetection fails, so it is only used in seldom cases.

We do not.

Dito. Show me a system with such "problem" after a fresh installation.

Security, soso. Well, since this rescue environment has an executable
shell with root permissions, it _may_ be a security hole, since you can
damage partitions easily, for example. To disable this shell, edit
/etc/mkinitrd/mkinitrd.conf and set DELAY=0. Then recreate the initrd
image (dpkg-reconfigure kernel-image-2.4.x-yz).
Gruss/Regards,
Eduard.
