This should have gotten the permissions right; -a implies |
| 21 |
--preserve=all. Not sure what happened there. |

The tar method you're looking for is: |
| 24 |
|
| 25 |
tar -C /old cpf - | tar -C /new xvpf - |
| 26 |

You'll probably not want to do the entire / in a single go, |
| 28 |
since /proc, /sys, and /dev (at least) should be skipped. |
| 29 |
Copy /old/sbin -> /new/sbin, etc. for all of the root |
| 30 |
folders that aren't their own partitions. The rest you can |
| 31 |
do the entire mount point at once, though I'm not sure you |
| 32 |
really need to copy /tmp either. |
| 33 |
|
| 34 |
You can also use rsync, dump/restore, and probably a dozen |
| 35 |
other tools to make this work. Google for "backup entire |
| 36 |
hard disk" and start reading :) |
