Are you sure about that today? And udev wasn't created to do everything
that devfs does. And devfs can't do everything that udev can (by
far...)
devfs has the effect of trying to load a module when a program looks
for the devices it provides-- while it can cause problems, it does
have a possibility to work better.
Sorry, but that model of loading modules is very broken and it is good
that we don't do that anymore (as you allude to.)
Interesting effects of switching my desktop from devfs to udev:
1. my DVD burners are left uninitialized until I manually modprobe ide-cd or (more recently) ide-scsi
Sounds like a broken distro configuration :)
2. my sound card is autodetected and the drivers loaded, but the OSS emulation modules are omitted; with devfs, they would be autoloaded when an app tried to use OSS
Again, broken distro configuration :)
