It should, you're right. |

However, that's a direct image straight across, fragmented files, even |
| 21 |
filesystem corruption if it exists on the source, and it's nice to take |
| 22 |
the opportunity to copy file-by file so everything gets defragmented and |
| 23 |
all the file nodes get organized, if possible, particularly since few |
| 24 |
Linux filesystems /have/ a defrag. Few need it very badly as long as a |
| 25 |
decent amount of free-space is kept on each filesystem (50% is great, 25% |
| 26 |
minimum for best operation, 10% and performance /does/ start to suffer), |
| 27 |
but it's still nice to organize it, getting files all in one piece and |
| 28 |
directories all located together, while one can. |

|

Also, new drives are generally larger and it's nice to be able to take |
| 31 |
the opportunity to reorganize the partitions. |
| 32 |
|
| 33 |
All those are reasons I like my simple partition/mkfs/copy-the-files-over |
| 34 |
method, but some folks don't seem to like that idea for whatever reason. |
