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.
