 Hi,
 
 if it is "just copy some code", then that should be done in order to be 
 able to boot from large devices. The time when the first 4 TByte discs 
 will be available may be soon ...
 The current hack in the bootloader code just try to get a valid 
 disklabel 64 block's later for booting from a raid1 device. That is a 
 very simple sollution.
 
 I will have look at gtp(8). Perhaps this will solve my problem.
 
 If disklabel is supposed to retire, than the sysinst should "always" 
 install systems useing gtp as soon as possible.
 On the other hand, the extensions to the disklabel structure does not 
 sound very expensive to me - I only have no time to do it (and test on 
 "all" architectures).
 
 best regards
