Hotpluggable devices are obviously a good thing.
Glad we agree. Now how do you handle hotpluggable devices (such as scsi drives) in userspace? Need scsi compiled in the kernel for booting. Compile it as a module as well? Whoahh... That just seems very ugly... Notify the user space daemon that something's disappeared so it can futz w/ /dev? Seems like an extra unneccessary step. That, and what permissions would it be set to when gets created? Need a config file, just the same as you'd need for devfsd.
