I'm copying Bdale, the maintainer of makedev. While trying to make a patch for this bug I noticed that MAKEDEV (both the 2.* in sid and the 3.* in experimental) doesn't know about nbd devices, but nb* devices, with the same major number (43). I don't know where to check if this is a makedev bug or not.
Also, lilo is checking /proc/partitions for major number 43, which doesn't seem a robust as it may change in the future, isn't there any alternative? -- Martín Ferrari
