All hardware in memory, then use something else to manage your modules (scripts, modules.conf, etc.) This is not a task for udev. +Q: But I love that feature of devfs, please? +A: The devfs approach caused a lot of spurious modprobe attempts as + programs probed to see if devices were present or not. Every probe + attempt created a process to run modprobe, almost all of which were + spurious. + Q: I really like the devfs naming scheme, will udev do that? A: Yes, udev can create /dev nodes using the devfs naming policy. A configuration file needs to be created to map the kernel default names - to the devfs names. See the initial udev.conf.devfs file in the udev + to the devfs names. See the initial udev.rules.devfs file in the udev release. It is the start of such a configuration file. If there are any things missing, please let the udev authors know. @@ -78,6 +84,20 @@ Q: How will udev handle devices found before init runs?
