Migrate primary disk (duplicate)

[Alexandre D.]

Here is the complete process I follow:

   sysctl kern.geom.debugflags=16
   dd if=/dev/zero of=/dev/${disk} bs=1k count=1
   fdisk -BI ${disk}
   disklabel -B -w -r ${disk}s1 auto
   disklabel -R ${disk}s1 generique.disklabel
   newfs /dev/${disk}s1a
   newfs /dev/${disk}s1d
   mount /dev/${disk}s1a ./mnt
   cd ./mnt
   dump 0uafL - / | restore xf -
   cd ..
   umount ./mnt
   mount /dev/${disk}s1d ./mnt
   cd ./mnt
   dump 0uafL - /usr | restore xf -
   cd ..
   umount ./mnt


-----generique.disklabel file-------
  a: 41943040        0    4.2BSD
  b:  2097152   *      swap 
  d: * *    4.2BSD 


------

If I do the same with /stand/sysinstall in stead of 
   dd if=/dev/zero of=/dev/${disk} bs=1k count=1
   fdisk -BI ${disk}
   disklabel -B -w -r ${disk}s1 auto

It works well.
