Hello, There are quite a few packages out there which depend on the cdrom interface. I'm wondering whether we could just provide the linuxish interface for it in e.g. sys/cdrom.h. Most of the ioctls should be working fine, only the data read ones would only work with a kernel implementation. That should bring us easy compatibility with a lot of packages, while leaving just a few bits to change for a userland-cd-driver-compatible interface. Thoughts? Samuel
