You can also use mknod directly :)

Error or feature?
Neither, its "ignorance" on the MAKEDEV side ...
My MAKEDEV does not know about and some other stuff either.
create a patch and submit it to MAKEDEV upstream...

> All the DRBD related HOWTOs do not write about this.
Point taken, should be improved.
# cd /dev ; for i in `seq 1 8`; do mknod nb$i b 43 $i ; done
Maybe we even add this to the make intall target?

Completely off track here. If version of driver changed block
device major, this would be very odd.

> Again: How check a version mix systematically?
By install date/ctime/mtime/md5sum/cmp.
In short: Don't.  Remove and reinstall.
