Not really. Yes, the current partitioning scheme will not make more than the |
| 22 |
160G available. But this can be changed easily later, all I need to do is |
| 23 |
call fdisk and add partitions. Or resize the last one. |

But that's much more complicated than just using dd or Ghost. It involves |
| 32 |
using a Linux rescue CD, mounting several file systems, using the right |
| 33 |
cp/tar/rsync syntax, and installing a new boot loader. With me telling the |
| 34 |
guy via phone what he has to type. |
| 35 |
If it's really necessary, oh well, than it has to be done. But if dd'ing the |
| 36 |
drive would work, I would vermy much prefer this. |
