Slackware and mdev (question)

I know from keeping an active study on Slackware that Slackware still maintains the legacy devfs rc.modules file to allow a system admin to select or edit in kernel modules to load on system startup without relying on udev to automatically detect and load everything.

I was wondering, if this file could be used with an alternative to udev, like mdev, since mdev lacks the auto-detection module loading feature, to allow Slackware to be used without udev present in the system provided you preloaded all modules using rc.modules at boot.

hotplug2 may be a better alternative than mdev. Despite the name, it uses the same kernel interface as udev and can load kernel modules.

I never used devfs much, but I thought it was simply a way to dynamically create device nodes. hotplug was a way to auto-load (modprobe) modules. rc.modules was just a way to manage manually loading your modules. You can just as well drop udev and start using rc.modules again. And of course, these days, udev is not needed for creating device nodes either. You loose automounting/device insertion information, but there are alternatives.
