No. Giving a major and minor number is simple. Creating a device node means: you have to define a policy. Now the kernel has to think about: - user id - group id - access rights - naming
These are the reasons why devfsd was/is necessary for devfs. A Kernel should only enforce a policy, it should not define it.
