You can't put a label on the whole disk device. Labels can only be put on FreeBSD slices. The "whole" device for the first FreeBSD slice is /dev/rsd1c, which has a different minor number than /dev/rsd1, although it may cover the same area. /dev/rsd1 didn't exist before 2.0.5. The whole disk device was named /dev/rsd1c. The whole FreeBSD slice is still named /dev/rsd1c and everything internal to it works the same as before. All the examples in the disklabel man page are of the form disklabel ... sd1 ... ^ no dev disklabel ... /dev/rsd1c ... ^^^^^ ^ disklabel adds the `/dev/' and the `c' automatically if and only if the original device name is absolute (i.e., doesn't contain a slash). Don't use an absolute device name unless you want to override the default. Bruce
