look at the manpage for rdev: 'The rdev utility [..] is an ancient hack [..].
[..] Use a bootloader like SysLinux or LILO instead'.

And sure it is a hack, since 
- this isn't usable on non-x86 systems.
- You may get problems with devfs, since this has no fixed major/minor for
some device, and rdev only puts just this major/minor into the kernel - not
the device name.
- it is just another way to specify the root device - there are already enough.
- (to be continued ...)

It is a tool from the very beginning of the linux kernel (pre-1.0), when 
there was no syslinux, lilo or else available as a bootloader.

Regards,

Josef
