>Description:
Currently, rump_etfs provides a direct block device mapping to
a host file.  It does not allow to register a disk(9) device.
Also, it does not allow to specify things like "this file is a cd".
>How-To-Repeat:

>Fix:
Maybe add another interface such as rump_etfs_register_disk()?
Then you could say register("/dev/cd0d", "/dev/cd", DEVTYPE_CD)
or something like that (the in-rump device node names might need
a little thinking).
